Nickel ore is the main sub-sulfide copper-nickel ore and nickel oxide ore, beneficiation and processing methods of the two are completely different. 

 Beneficiation of copper-nickel sulfide ore dressing equipment: 

 Copper-nickel sulfide ore beneficiation methods, most notably flotation, magnetic separation and re-election is usually secondary beneficiation methods. Flotation of copper-nickel sulfide ore, often with the flotation of sulfide copper minerals, collector and frother. Determine the flotation process, a basic principle is to prefer the copper into the nickel concentrate as much as possible to avoid nickel to enter the copper concentrate. Loss of copper concentrate in the nickel smelting process, the copper in the nickel concentrate to get a more complete recovery. Copper-nickel ore flotation has the following four basic processes. 
 Direct flotation flotation or part of the process than the nickel content is much higher, can use this process: copper ore, copper election into separate concentrates. The advantages of this process is direct access to lower copper concentrate containing nickel. 
 1) flotation processes: for sorting copper nickel ore is lower than the proceeds of copper-nickel mixed concentrate direct smelting into nickel matte. 
 2) Mixed - optimization of the flotation process: from ore flotation copper-nickel, elected from the mixed concentrate carved with low nickel copper concentrate and copper nickel concentrate. The nickel concentrates by smelting, nickel matte, high-nickel matte flotation separation. 
 3) Mixed - flotation and recycling part of the nickel: When are very different in the various nickel minerals in the ore can be floating, flotation of copper-nickel from tailings from the flotation tailings further recovery may be poor floatability of nickel-containing minerals. 
 Copper nickel smelting harmful impurities in the copper-nickel ore, copper grade of industrial recovery value, the copper-nickel separation is an important topic in the copper-nickel ore dressing. Copper-nickel separation technology is divided into mixed concentrate separation of the copper-nickel and high nickel matte separation process two. Typically, the former for the copper-nickel minerals coarse grain size to each other embedded in the cloth, not very close to ore, which is used to fine grain size of copper-nickel minerals to each other embedded in the fabric is very dense ore. 

 Nickel ore beneficiation process include: 

 Broken for the three sections of a closed circuit; grinding ore grinding and flotation processes into three sections, three sections of the flotation process. Copper-nickel sulfide ores using pyrometallurgical. Jinchuan Nickel Mine is no exception, the basic process of sub-preparation (roasting) - melting - blowing - Refining (electrolysis) and other links. Because mine is a serpentine type of ore, copper and nickel minerals with each other dense disseminated directly by mechanical beneficiation of copper-nickel separation is difficult, so a high nickel matte flotation separation technology. Melting the mixed copper-nickel concentrate by the converter into a high-nickel matte, and then crushing and grinding the float process, the final electrolysis into the final product - electrolytic nickel. 
 Jilin rock ore is copper-nickel ore, its beneficiation process using three sections of a closed-circuit crushing stage grinding, copper-nickel mixed - flotation separation, dehydration of three segments of nickel concentrate, copper concentrate two dehydration process. 

 The nickel oxide ore crushing, screening and other processes in advance to remove weak degree of weathering and low nickel-containing chunks of bedrock. Nickel oxide nickel ore is often dispersed in the gangue minerals in isomorphous, and the granularity is very fine and therefore can not be enriched mechanical beneficiation methods, only the direct smelting. 
 Smelting nickel oxide ore enrichment methods can be divided into the fire and wet two categories. The former can be divided into-made sulfur melting, the method of nickel-iron and ferrite France; the latter there are reductive roasting - atmospheric ammonia leaching, high pressure acid leaching.
