Making a complete list of gold mining equipment starts with defining the type of gold mining you are doing and the budget you have at your disposal. The type of mining relates to hard rock,eluvial, or placer; alluvial deposits. The capital budget you have to invest in buying your equipment with dictate the scale at which you want to mine and influence the long-term operating costs of your mining operation.
Since most of the information online provides lists of gold mining equipment for amateur level mining with equipment like: gold pans, metal detectors, mini sluice box, blue bowl, geologist rock pick, soil scoop, hand screens/classifiers. The items listed just now fall closer to gold prospecting tools and equipment than actual mining.
I will present here what I consider are major equipment lists for 3 types of mining operations. Remember now, a metallurgist is writing. This will not be flawless and since my speciality is process equipment, that is mostly what will be discussed.
Some amateur level gold prospecting equipment such as metal detectors are often classified as mining equipment by small miners/prospectors operating as a hobby. These items include but are not limited to:
Gold is a dense, soft, shiny, malleable, and ductile metal. It is a chemical element with the symbol Au and atomic number 79. It has a bright yellow color and luster traditionally considered attractive, which it maintains without oxidizing in air or water. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements, solid under standard conditions. The metal therefore occurs often in free elemental (native) form, as nuggets or grains in rocks, in veins and in alluvial deposits.
Gold ore processing plant is widely used in gold ore crushing and grinding process to resize and pulverize gold ores into 10mm to smaller than 1mm particles. As gold ores VHN hardness is between 60 and 105, SBM design gold ore crushing plant and grinding machine that can process gold ore. SBM gold ore processing plant includes mainly two series: crushing and grinding machines, both of which are welcomed by our customers. SBM gold ore crusher can produce gold products with the size between cm and mm. And our gold ore grinding machine can process gold ore into powder of nm grade.
State and gold content of gold in the mineral structure can be divided into the gold mineral gold deposits of gold minerals, gold-bearing minerals and gold - bearing minerals three categories. Independent minerals, means the so-called gold gold gold minerals and gold minerals in the form of output, it is the most important modes of occurrence of gold in nature, industrial development and utilization of the main object. So far, the world has found 98 gold minerals and gold-bearing minerals, common only 47 species, and direct industrial use mineral only 10 kinds of.
3) in the industrial and scientific and technological applications. Infrared reflectance close to due to the gold have unique perfect nature, it has a high resistance to corrosion stability; good electrical conductivity and thermal conductivity; the gold nuclei having a larger neutron capture cross-section; ; also widely used in the most important modern high-tech industry, and electronic technology, communications technology, aerospace technology, chemical technology, medical technology.
Most of the gold processing plant use jaw crusher as the primary crushing. CSB cone crusher is used as the intermediate crushing. The CSD cone crusher is as the fine crushing. The equipment potential to improve mineral production capacity, crushing process transformation, improve the utilization factor of the grinding machine, taken measures to implement the more crushing and less grinding to reduce the particle size of ore into the mill.
Flotation machine (also called Flotation separator) is applicable for the separation of nonferrous metal and ferrous metal and nonmetal, such as fluorite and talc. The impeller is driven by V-belts, which can bring the centrifugal effect to form the negative pressure. On the one hand, to inhale sufficient air to mix with ore pulp; on the other hand, to stir ore pulp and mix with medication to form the mineralized froth. To adjust the height of flashboard to control the liquid level and make the useful froth scraped by loam board. When flotation machine works, slurry is inhaled from the bottom of the trough to the space between impellers. Meanwhile, the low pressure air send by fan is sent to this area through the air distributor in the hollow shaft. After sufficient mixing, the slurry is pushed out by the impeller, and then goes to the whole trough. When the froth rises to the stable level, after the enrichment processing, froth overflows to the froth trough from the overflow weir. Another part of ore slurry flows to lower part of impeller for the remixing with air. The remained slurry flows to the next trough until it becomes residue.

(A) comprehensive utilization of mineral resources, inadequate laws and regulations, the comprehensive utilization of mineral resources, preferential policies are not in place. Adopting both rich and poor, low-grade ore and to carry out the comprehensive use of recycling useful components associated with the taxes charged according to the amount and quality, increase the use of cost, profit margins are low due to the recovery of this part of the resources even needed capital subsidy, , engage in comprehensive utilization but affect the economic efficiency of enterprises.
(B) loss of mineral resources, waste and destruction Most of the gold mines, especially small-scale mining is often the case where the low level of exploration under construction. Mine put into production, infrastructure, technological transformation at the same time, the majority of small businesses in the metallurgical process technology, low management level, coupled with the initial mining program ill-considered, often resulting in a large loss of resources, waste and destruction.
(D) investment in science and technology and personnel training is not enough emphasis Currently, the gold mine of comprehensive utilization of research are still weak, the depth and breadth of the comprehensive utilization of mineral resources research is not enough. On the one hand, the industrial sector dispersion of Geology and Mineral scientific research strength is not concentrated, apparatus, equipment, poorly equipped, do not form a fist. On the other hand, the comprehensive utilization of mineral resources, a serious shortage of basic research forces. Deployment of geological prospecting work, no deployment and comprehensive evaluation study on comprehensive utilization pilot study. Existing scientific research with low conversion rates.
Once extracted, the gold ore is pulverized to prepare it for refining. The gold is refined with one of four main processes: floatation, amalgamation, cyanidation, or carbon-in-pulp. Each process relies on the initial grinding of the gold ore, and more than one process may be used on the same batch of gold ore.
In this refining circuit, we can use electrowining cells, electrorefining cells and remelt furnace to refine gold ore. we also can use filter presses, mercury retorts and induction refining furnace to purify gole.

After gold ore mined, firstly go through crushing process. In the gold ore coarse crushing process, jaw crusher is used as gold ore primary crusher. After coarse crushing process, screen out the fine gold ore, the gild ore with diameter more than 10 mm go through secondary crushing process, in this crushing process, standard CS series cone crusher is used. In some large gold concentrator, there is fine crushing process after secondary crushing. In this fine crushing, short head CS series cone crusher is used as gold ore crushing machine.
After crushing process, the crushed gold ore enter into ball mill evenly through vibrating screen. Ball mill is essential gold ore beneficiation machine used to grind gold ore into powder less than 200 mesh. Gold ore powder go through classification and flotation to make pure gold.
Small scale gold oremillingequipment to refer to mining characterized by a labor force that is not formally trained in mining and uses rudimentary techniques for prospecting, extracting, and processing of gold. Nowadays almost all small scale miners use mechanized methods, including crushers, hydraulic machines, backhoe excavators, tractors and other industrial devices.
According our survey data that small scale gold mining is of crucial importance to the livelihoods of many families in some areas. In some villages, most of s obtain regular income from mining members of the or the extended family. These incomes not only include the wages from mine laborers, but also earnings from people working in the mining service economy. In other cases gold miners may put together money to keep the village generator running and hence provide electricity. It is no exaggeration to say that small scale gold mining carries the economies of these areas.

Hard rock mining is the process of extracting metals and minerals encased in rocks (primary deposit). Hard rock ore can contain metals, minerals such as gold, platinum, silver, iron, copper, manganese, zinc, nickel, tin and lead, zircon, etc.
DOVE Semi-stationary Hard Rock Plants unique designs are embedded in every single one of their components to insure efficient operations and 100% recovery of the Gold, Tin, Iron, Tantalite, Manganese and other metals and minerals production, with no loss.
Ore feeding, Crushing (Coarse and Fine), Grinding (or milling), Sizing (screening and classification) and Concentration (separation and recovery) are the three most important steps that are involved in ore processing by Hard Rock Plants. Overlooking any short of these steps will result in lack or reduction of recovery, as well as the loss of the valuable minerals.
In a hard rock plant, the concentration (recovery and separation) stage is achieved by a method scientifically called Gravity Separation. The separation occurs when the metals and mineral are subjected to a variety of forces in a medium (e.g. water, air, other heavy medium) to trigger a response, which is usually enhanced resistance or accelerated settling time of said metals and minerals, depending on their specific gravity.
consists of a large hopper designed to feed the ore to the rest of the hard rock plant plant. The hopper, in a hard rock, usually allows for dry feed of the rocks to the plant. It is designed for a direct feed by earth moving equipment. The size of the feed will depend on the plants capacity (Tons Per Hour).
DOVE Ore Feed Hoppers are supplied in wide range of capacities, and are designed and engineered as parts that fit to make the hopper. This feature allows the hopper to easily be shipped in standard containers and rapidly be assembled and installed once on site.
it is a device set between the hopper and belt conveyor, or any equipment fed by the hopper.
