Nickel Salt Non-ferrous Metal Raw Materials
Foshan Qiruide Additives Co., Ltd | Updated: Jul 03, 2017

Nickel Salt Non-ferrous metal raw materials

As of the end of 1995, China has proven 84 nickel ore area, located in 18 provinces, autonomous regions. The reserves of nickel are 785.31 million t, of which A + B + C is 47.9% of the reserves of 376.39 million t. Such as China's industrial reserves (A + B + C level) compared with the basis of Western countries, China's reserves in Cuba (reserves of 23 million t), New Caledonia (reserves of 15 million t), Canada (Reserves based on 11 million t), Australia (reserves of 6.8 million t), Brazil (reserves based on 4.3 million t), the Philippines (reserves of 11 million t), the Philippines (reserves of 11.8 million t) ), Ranked ninth in the world.

60 years due to Gansu Jinchuan copper sulfide nickel ore exploration success, nickel reserves increased by more than 1 times in 10 years, marking China's nickel ore reserves of the world's important position. Since 1975, nickel reserves are basically stable at 760 ~ 780 million t.

China's nickel ore resources are relatively rich, it is predicted that the amount of resources in 900 million t or so. The most far-sighted areas are the northern hills of Huangshan, Dome and Tarim Basin in Hami, Xinjiang.

Reserves distribution

China's nickel ore distribution on the region, mainly in the northwest, southwest and northeast, its reserves accounted for the proportion of the total reserves were 76.8%, 12.1%, 4.9%. (11.6%), Yunnan (8.9%), Xinjiang (11.6%), Yunnan (8.9%), Xinjiang (11.6%), Yunnan (8.9%), Yunnan (11.9%), Yunnan (8.9%), Jilin (4.4%), Hubei (3.4%) and Sichuan (3.3%).

Prospecting breakthrough

The Central Geological Exploration Fund has made a breakthrough in the project "Ridge-Nanking Ridge Nickel Ore Survey" in Ruoqiang, Xinjiang. The results of the census conducted by the Fund in collaboration with other social funds show that the region has a total of more than one million tons of nickel resources and the size of the deposit is large. It is estimated that the central geological prospecting fund of this investment directly pull the social exploration funds nearly 100 million yuan, a new mechanism for the country to find another major achievement.

Nickel is a scarcity of non-ferrous metal raw materials in the field of machinery manufacturing and other fields have a wide range of applications, China's imports increased year by year. It is understood that since its inception in 2006, the central geological survey fund project has been submitted to the important minerals of large and medium-sized mineral field 53.

It is understood that, as of the end of 2011, the whole mining area to explore a total of 1.28 million tons of nickel metal resources. Census also found that the survey area thick ore layer has not yet fully controlled, the scale is expected to expand the ore, ore grade to further improve the nickel, nickel and other resources, the scale of resources is expected to exceed 200 million tons.

Processing of mineral processing

Nickel ore is mainly divided into copper sulfide and nickel oxide ore, both of the mineral processing and processing methods are completely different.

Copper sulfide

Copper sulfide nickel ore mineral processing methods, the most important is the flotation, and magnetic separation and re-election is usually an auxiliary beneficiation method. Flotation of copper sulfide nickel ore, often used flotation copper sulfide minerals and foaming agent. One of the basic principles for determining the flotation process is to prefer copper to the nickel concentrate and avoid nickel as much as possible into the copper concentrate. Because copper in the copper concentrate in the process of loss of large, and nickel concentrate in the copper can be more complete recovery. Copper and nickel ore flotation has the following four basic processes.

Directly flotation or partial pre-flotation process: When the ore in the ore is much higher than the nickel content, this process can be used to select the copper as a separate concentrate. The advantage of this process is that copper concentrates with low nickel content can be obtained directly.
