100tpd copper oxide flotation processing plant in tanzania - copper - news - xi'an desen mining machinery equipment co.,ltd

In 2015, a copper mine customer came to our company and hoped that we could help him flotation of the copper mine in Tanzania. Before doing the formal beneficiation, the customer brought his ore to our factory and did the ore taste analysis and flotation experiment. The experimental results are as follows:

Combining the above experimental results and the customer's strength of our factory, the customer decided to choose us to do the copper ore dressing test for him. The experiment process is as follows: feeding-crushing-grinding-flotation.

The main equipment included are:Feeder-Jaw Crusher-Hammer Crusher-Ball Mill-Spiral Classifier-Mixing Barrel-Flotation MachineAt the same time, flotation reagents are also used.The project began infrastructure construction in April 2016 and successfully ran in May. The highest taste of copper and gold powder can reach 52%.

Commonly used beneficiation methods include gravity separation, flotation, magnetic separation, electrical separation and chemical beneficiation. Even the same type of copper ore, it is necessary to design the most appropriate process according to local conditions, and cannot be copied completely.

The gravity separation method sorts minerals according to their relative density (usually called specific gravity). Mineral particles with different densities are subjected to the action of fluid power and mechanical force of various mineral processing equipment in the moving medium (water, air and heavy liquid), resulting in suitable loose stratification and separation conditions, so that the mineral particles of different densities are separated.Currently, gravity separation is only used to select copper ores with coarser inlays, and is especially suitable for copper oxide ores with higher density. Commonly used gravity separation equipment includes heavy medium beneficiation, jig and shaker.

The flotation method is based on the difference in the physical and chemical properties of the mineral surface, processed by the flotation agent, and the mineral is selectively attached to the bubbles to achieve the purpose of separation. The beneficiation of non-ferrous metal ores, such as copper, lead, zinc, sulfur, molybdenum, etc., is mainly treated by flotation; some ferrous metals, rare metals, and some non-metallic ores, such as graphite ore, apatite, etc. are also used for flotation Law selection.

The magnetic separation method is based on the different magnetic properties of minerals. Different minerals are subjected to different forces in the magnetic field of the magnetic separator, so as to be sorted. It is mainly used for sorting ferrous metal ores (iron, manganese, chromium), but also for sorting non-ferrous and rare metal ores.

The electrical separation method is based on the difference in mineral conductivity. When the mineral passes through the high-voltage electric field of the electric separator, due to the different conductivity of the mineral, the electrostatic force acting on the mineral is also different, so that the mineral can be separated. The electrical separation method is used for the separation of rare metals, non-ferrous metals and non-metallic ores. At present, it is mainly used for separation and beneficiation of mixed coarse concentrates, such as separation of scheelite and cassiterite, beneficiation of zircon, and beneficiation of tantalum and niobium ore.

Chemical beneficiation is a mineral processing process based on the difference in the chemical properties of minerals and mineral components, using chemical methods to change the mineral composition, and then enriching the target components by other methods. For example, leaching copper ore containing malachite with dilute sulfuric acid changes the mineral composition, that is, malachite becomes a copper sulfate solution, and then replaces copper ions in the solution with iron filings to obtain metallic copper.

Copper beneficiation technology basically includes crushing, grinding, grading, sieving, sorting, drying and other processes. Each process is connected by a conveyor to ensure the integrity of the connection between the various processes.1. Copper smeltingCopper concentrate is the primary mineral material for copper smelting, and its smelting methods include fire method and wet method. At present, the fire method is the main method, and the wet method is in the experimental discussion period.

2. Washing and screeningOre washing equipment uses water flushing and mechanical scrubbing to separate the ore from the mud. Commonly used ore washing equipment include ore washing screen, cylinder trommel scrubber washing machine and trough type washing machine.Ore washing work is often accompanied by sieving, such as flushing directly on the vibrating screen for cleaning or sending the ore (net ore) obtained by the ore washing machine to the vibrating screen for sieving. The sieving can be used as an independent work, separating the different sizes and grades of copper concentrate commodity supply with different uses.

Type Agitating flotation machine, Self-priming, aeration flotation, flotation column. ModelXJK, SF, GF, CHF, XJC, etc. Contact us for specific & quick selection.

Flotation machine (floatation machine, planktonic concentrator) in the mineral processing plant, mainly used for separating copper, zinc, lead, nickel, gold, and other non-ferrous metal. TypeXJK series agitation impeller flotation machine (Seldom used, small capacity); SF flotation machine (Larger volume, better flotation effect); Pneumatic flotation machine (aeration and agitation, high capacity). Corollary equipmentIn front: one or two sets of mixing tank for flotation agent agitation and slurry pulp agitation. Behind: concentrate pond, thickener or filter Flotation cell According to the ore grade, mineral type and processing capacity to choose, determine the number of the flotation cells. It is recommended that carrying out the mineral flotation tests to obtain the best procedure plan, like pulp density, time, reagent selection, etc. Flotation reagentfoaming agent, collecting agent, activating agent, inhibitor, etc. BrandsWemco flotation unit, Fahrenwald Denver, Callow, BGRIMM, etc. How to select mining flotation machine1. According to the nature of the ore (washability, feed particle-size, density, grade, pulp, pH, etc.) and flotation plant scale choose the appropriate flotation machine. 2. The concentration operation is mainly to improve the ore concentrate grade. The flotation foam layer should be thin so that separates the gangue. It is not appropriate to use a flotation machine with a large aeration volume. Therefore, there are differences between the froth flotation machine of concentration, roughing and scavenging. 3. JXSC engineer team here to help do flotation mining machine selection, price inquiry, flowsheet design.

Flotation machine structureThe metallurgist flotation mainly made up of slurry tank, mixing device, aeration device, mineralized bubble discharging device and motor. Flotation machine working principleFlotation process refers to the flotation separation in mineral processing. In the flotation machine, the ore slurry treated with the added agent, by aeration and stir, some of the ore particles are selectively fixed on the air bubbles and floats to the surface of the slurry and is scraped out. The rest is retained in the pulp, thus achieve the purpose of separating different minerals. The complete froth flotation process in metallurgy consists of rougher flotation, concentrate flotation and scavenging flotation. Flotation methodFroth flotation of sulphide ores, mainly have differential flotation and bulk flotation process, improve the flotation recovery rate of fine - particle. Flotation cell manufacturerJXSC specializes in the production of a full set of mineral processing equipment, and cooperates with the Mining Research Institute to design a scientific and reliable mineral processing flowsheet, supply gold flotation, copper flotation, zinc flotation, and the like ore flotation units.
