Chrome ore beneficiation plant

chrome ore beneficiation

The Chrome ore beneficiation plant is used to get chrome concentrate. Chromite is conveniently milled to recover a fine concentrate by gravity and elutriation techniques. Further gravity separation and elutriation steps yield the specific grain sizes and reduced levels of impurities, such as silica, required for the chemical and foundry sand markets.

Chrome ore beneficiation process

The chrome ore beneficiation project comprised of:

Ore crushing plant: Chrome ore crushing plant is used to crush and grind chrome ores into small particles for further Chrome ore beneficiation process. In this Chrome ore crushing plant, there are several types of crusher and grinding machines used. Jaw crusher is used for chrome ore coarse crushing process, Impact crusher and cone crusher are used in chrome ore fine crushing plant. Ball mill and rod mill are used for grinding crushed chrome ores into powder for beneficiation process.

Storage section: After chrome ore crushing and grinding process, small chrome ore grains are stored for next chrome ore beneficiation process.

Concentration system: Chrome ore concentration plant is used for ore mineral concentration. It is the main step for chrome ore beneficiation plant. Gravity separation is the best proven and accepted technique of concentrating minerals and has been used as a primary form of mineral concentration. Due to its high efficiency and low cost, gravity separation is always the first consideration in any flowsheet development program and always features in any flowsheet where there is sufficient differences between the specific gravity and particle size of the valuable and gangue minerals.

Tailings handling and water recycle system: The Chrome concentrate is coarse grained (98.79% is >0.038 mm size) while the Chrome tailings is fine grained (44.69% is < 0.038 mm size). The Chrome tailing was cleaned in ball mill and treated in tabling to obtain a concentrate with 51.8% Cr2O3. The bulk rejects in the experiments was fine grained (50.51% is < 0.038 mm size), contained 10.56% Cr2O3 and 16.47% chromite values out of which 11.10% is distributed in minus 0.038 mm size fractions.

Product dewatering and handling system: It is the late step for the chrome ore beneficiation plant. Sludge dewatering is typically handled by a Filter Press. After processing a batch of "sludge" the filter press is emptied of “chrome cake” which is a semi solid of approximately 20-35 % solids. Chrome cake is high in chrome and sulfite and should be disposed of according to environmental regulations.

Chrome ore concentrate machine

Spiral concentrator is the best chrome ore concentrating equipment for chrome ore beneficiation plant, it has been used in to enrichment the particle size 0.3-0.02 millimeters fine grain like iron, tin, chromite and ilmenite. This chrome ore concentrate machine is made of the fiberglass lined with wear-resistant polyurethane and corundum cover; The advantages are light, moisture proof, anti-rust, wear proof, anti corrosion and no noise, properly suitable for the different feeding particle sizes and grades. It is the domestic advanced level, the new highly effective equipment.

SBM is chrome ore concentrate machine manufacturer in China, and offer types of machines for chrome ore beneficiation plant in South Africa, India, Kazakhstan, Zimbabwe, Finland, Iran, Brazil, USA, China, Oman, Pakistan, the Sudan, Malaysia, Turkey, Mozambique, Madagascar, Albania, Turkey, Philippines and New Caledonia. We also design chrome ore beneficiation process for production.
