Industrial recycling of cobalt-nickel ore Cobalt-nickel ore is one of the most important resources in industrial production. Cobalt nickel is an important component of stainless steel production and the battery industry. It is an important component of cobalt-nickel alloys, high-temperature alloys, and oxidation and corrosion resistant alloys. It is often used for alloy steel for steelmaking, plating and welding materials. And catalysts, coatings, magnets and other products. The recycling of cobalt-nickel ore should not be neglected.
Cobalt-nickel ore recycling can effectively reduce the damage caused by mining ore from the ground and reduce the cost of mining. The recovery of cobalt-nickel ore has been successful in many mining areas, and the technology for recycling ore is becoming more and more mature. In recent years, with the development of the mining industry, questions such as how to ensure safe recycling of cobalt-nickel ore, how to effectively reduce costs, and how to upgrade technology have concerned many professionals and miners.
The industrial recycling process is an important factor in determining the success of cobalt-nickel ore recycling. Generally speaking, the recycling process of cobalt-nickel ore is divided into three stages, namely crushing, magnetic separation, and extraction.
At the stage of cobalt-nickel ore crushing, the ore is crushed and crushed, broken and ground into a fine powder (usually 20~25 mm). These fine particles enter the crusher and use the hammer to hit the cobalt-nickel ore to achieve fragmentation of the ore particles. When the granularity of the ore particles is less than 10mm, the metal particles in them will enter the magnetic separator for sorting.
The metal particles of cobalt-nickel ore are sorted and separated by magnetic separator. The metal particles with strong magnetic properties will be adsorbed on the surface of the magnetic separator, so that the non-magnetic metal particles can be separated from the magnetic force.
Finally, cobalt-nickel ore is separated, extracted and manufactured by acid leaching. This method is simple and effective. It uses hydrochloric acid or sulfuric acid to leach out cobalt and nickel. The leached slurry is then separated and extracted in a centrifuge or filter press.
Cobalt-nickel ore recycling is an important step in the development of the mining industry. It not only effectively reduces the impact of mining on the environment and reduces the cost of mining, but also greatly improves the comprehensive utilization of mineral resources. In any case, it is necessary to select advanced technology, mature and reliable equipment, and a complete set of cobalt-nickel ore recycling program to ensure that the industrial recycling of cobalt-nickel ore is carried out in an orderly and efficient manner.
