Embodiment 1
[0048] This embodiment provides a method for selecting copper and nickel from a copper-nickel ore, wherein the copper-nickel ore has a copper grade of 0.95% and a nickel grade of 0.92%.
[0049] The main valuable elements of the copper-nickel ore are copper and nickel, followed by recyclable precious metals gold, silver, platinum and palladium. Nickel minerals are mainly pyrite and pyrite, copper minerals are mainly chalcopyrite, chalcopyrite and a small amount of chalcopyrite, and other metal minerals are mainly pyrrhotite, pyrite, magnetite Ore, chromite, rare and precious metal ore are tellurium silver ore, natural gold, silver gold ore, gold and silver ore, tellurium bismuth palladium ore, tellurium bismuth (platinum) palladium ore, arsenic platinum ore, etc. The gangue minerals are mainly serpentine stone. Copper and nickel minerals are closely related to magnetite, and magnetite usually grows at the sulfide grain boundary.

Embodiment 2
[0077] This embodiment provides a method for selecting copper and nickel from a copper-nickel ore. The difference from Example 1 lies in the ore feeding. The copper-nickel ore in this embodiment has a copper grade of 0.87% and a nickel grade of 1.30%.
[0078] The main valuable elements of the copper-nickel ore are copper and nickel, followed by recyclable precious metals gold, silver, platinum and palladium. Nickel minerals are mainly nickel pyrite, copper-nickel iron ore, purple sulfur nickel ore, copper minerals are mainly chalcopyrite, chalcopyrite, chalcopyrite, and other metal minerals are mainly pyrrhotite, tetragonal pyrite Ore, pyrite, magnetite, rare and precious metal ore are natural gold, silver-gold ore, gold-silver ore, bismuth tellurium palladium ore, bismuth tellurium (platinum) palladium ore, etc. The gangue mineral is mainly serpentine. The structure of the ore is complex, and a large amount of magnetite and magnesia-bearing gangue minerals are filled in the ...
