Metals you can extract include: gold, silver or other of the precious group as well as the classic base metals; copper, lead, zinc, nickel, molybdenum. Much of our ultra-small scale equipment allows you to process from just a few kilo (pounds) per day and work on your passion for a small budget.

You can buy from us mineral processing equipment starting from crushing, grinding, classification, dredging, gravity separation, flotation, pumps, water treatment and smelting. A line of ovens, furnaces and laboratory equipment is also available.

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:

different types of explosives used in mining

different types of explosives used in mining

Are civil and military explosives the same? In other words, are we using the same explosives in mining and warfare? Well, yes and no. From the ninth century AD (though the historians are still uncertain about the exact date of its invention) to the mid-1800s, black powder was the only explosive available. A single type of explosives was therefore used as a propellant for guns and for blasting purpose in any military, mining and civil engineering application.

The Industrial Revolution carried discoveries in explosives and initiation technologies. A specialization principle, therefore, operates between the military and civil application of explosives thanks to new products economics, versatility, strength, precision or capability to be stored for long periods without significant deterioration.

Nevertheless, military-like shaped charges are sometimes used in the demolition of building and structures and ANFOs characteristics (ANFO is an acronym for Ammonium Nitrate Fuel Oil mixture), though originally developed for use in mining, are also appreciated by the army.

The so-called "low-order explosives" or "low explosives," such as Black Powder, tend to generate a large number of gasses and burn at subsonic speeds. This reaction is called deflagration. Low explosives do not generate shock waves.

Propellant for gun bullet or rockets, fireworks, and special effects are the most common applications for low explosives. But even though high explosives are safer, low explosives are still in use today in some countries for mining applications, basically for cost reasons. In the US, Black Powder for civil use is outlawed since 1966.

On the other hand, the "high-order explosives" or "high explosives," such as Dynamite, tend to detonate which means they generate high-temperature and high-pressure gasses and a shock wave traveling at about or greater than the speed of sound, that break down the material.

Contrary to what most people think high explosives are often safe products (especially as far as secondary explosives are concerned, refer here below). Dynamite can be dropped, hit and even burned without accidentally exploding. Dynamite was invented by Alfred Nobel in 1866 precisely for that very purpose: allowing a safer use of the newly discovered (1846) and highly unstable nitroglycerine by mixing it with a special clay called kieselguhr.

Due to their extreme sensitivity to heat, friction, impact, static electricity. Mercury fulminate, lead azide or PETN (or penthrite, or more properly Penta Erythritol Tetra Nitrate) are good examples of primary explosives used in the mining industry. They can be found in blasting caps and detonators.

They are sensitive especially to heat but will tend to burn to detonation when present in relatively large quantities. It may sound like a paradox, but a truckload of dynamite will burn to detonation faster and easier compared to a single stick of dynamite.

Which is why they are, under certain conditions, officially classified as non-explosives. They are nonetheless potentially extremely hazardous products, as demonstrated by the devasting accidents involving Ammonium Nitrate in recent history. A fire detonated approximately 2,300 tons of ammonium nitrate caused the deadliest industrial accident in U.S. history that occurred on April 16, 1947, in Texas City, Texas. Close to 600 casualties were recorded, and 5,000 people were injured. Hazards link to ammonium nitrate have been more recently demonstrated by the AZF factory accident in Toulouse, France. An explosion occurred on September 21, 2001, in an Ammonium Nitrate warehouse killing 31 people and injuring 2,442, 34 of them seriously. Every window was shattered within a radius of three to four kilometers. Material damages were extensive, reported to be in excess of 2 billion Euros.

different types of mining equipment - every single topic

The mining sector is one of the most demanding and dangerous industry sectors, because the miners are surrounded by various hazardous items and they use different kinds of mining equipment and machines. Strong, powerful and durable mining equipment is essential for the mining sector, because the mining machines are the basic tools for the miners with which various valuable ores and minerals are being extracted from the ground. Unlike in the past when the miners used only hand made tools, today the miners and the mining sector enjoys the benefits provided by the modern mining equipment and machines which are specifically designed and produced for various mining purposes. The modern mining equipment is generally powered by electricity and hydraulic energy.

Different mining equipmentis used for specific mining projects. Generally, the mining equipment that is used in every mining site all over the world includes: drilling machines, shredders, drill rigs, blasting equipment, blasting machines, hammers, mining locomotives, industrial crushers, loaders, etc. Other examples for mining equipment and machines which are also heavily used for standard mining operations include: ventilation fans, tractors, earth movers, rock dusters, cutting machines, water jet systems and pumps, dozers, dump trucks, forklifts, cranes, and many other useful mining machines. A light mining equipment is used for a variety of mining purposes. This equipment improves significantly the efficiency and the speed of the mining operation, while ensuring superior and high quality results in the mining processes. The light mining equipment is generally consisted of LED or laser, heat sink, focusing cone or magnetic switch, sluice boxes, various digging tools, metal detectors, etc. This light mining equipment is generally used for gold extraction.

There is also a mining equipment specifically designed for surface mining operations, like area mining, contour mining, open pit mining, and quarrying. This mining equipment is consisted of various machines, such as: rock drills, paving breaker, wagon drill, DTH hammer, pneumatic crawler drill, drill steel grinder, cross bit grinder, and many other machines. All these mining machines are used for specific surface mining operations. In addition, special mining equipment is used for sub-surface mining operations, like draft mining, shaft mining, slope mining, borehole mining, hard rock mining, etc.

The selection of the right mining equipment is essential for achieving better results and for increased productivity. Many features, criteria and factors need to be closely considered when choosing a mining equipment for specific mining tasks. Two very important factors for choosing the right mining equipment are the durability and the strength of the mining machines. The overall cost is another important factor that needs to be carefully considered.
