Nickel ore is mainly divided into copper sulfide nickel ore and nickel oxide ore. 2 Nickel boundary and industrial grade The nickel sulfide ore can be divided into the following three grades according to the nickel content. The ore-rich ore-poor ore needs to be ore-selected , and the ore-rich ore can be directly smelted into the furnace. The ore of the nickel sulphide deposit is divided into: according to the vulcanization rate, that is, the ratio of nickel to total nickel in the sulphide state: Primary ore: SNi/TNi>70% Mixed ore: SNi/TNi45～70% Oxidized ore: SNi/TNi<45% Nickel silicate ores by magnesium oxide content is divided into: Iron ore quality: MgO <10% Ferrous magnesia ore: MgO <10~20% Magnesium ore: MgO>20% 3 Nickel concentrate quality standards (1) Nickel concentrate quality standard (YB742-82) This standard is applicable to nickel concentrate obtained from beneficiation of copper sulfide nickel ore for nickel smelting. Note: Co and Pt should be reported as valuable elements. (2) Nickel-sulfur concentrate quality standard This standard is applicable to nickel-sulfur concentrate obtained from high-altitude nickel ore dressing, power supply solution and nickel powder production. 4 copper-nickel and other metals major mineral minerals 1, copper minerals Chalcopyrite, ingot copper, copper blue, chalcopyrite, porphyrite 2, nickel minerals Nickel pyrite, needle sulfur nickel ore, nickel pyrrhotite, nickel silicate, purple sulfur nickel iron ore 3.

When the nickel grade does not reach the target and copper can form a separate ore body, the index can be performed in copper. In addition to copper, iron, Cr, Co, Mn, Pt elements, Au, Ag, Se, Te are often associated. In the serpentine , talc and other deposits contain high Ni, often have recycling value. 6 Copper-nickel ore multi-element analysis project 7 copper nickel phase (1) Copper phase Primary copper sulfide, secondary copper sulfide, combined copper oxide, free copper oxide (2) Nickel minerals Nickel sulfide, nickel silicate, nickel sulfide Endless pasting belts used for automatic pasting of battery grids on pasting machine (Hadi, Sovema, Wirtz, Mac, Winkel or any type of home made pasting machine).
