  • The process grain-size of a copper-nickel ore is superfine.At the level of less than 0.01mm the content of chalcopyrite,pentlandite and pyrrhotite is 88.57%,93.58% and 75.71% respectively,which leads to copper and nickel containing each other seriously.In the experiment reagents were removed from the copper-nickel bulk flotation concentrate first,then CaO and H2SO3 were used as combined depressant and Z-200 was used to strengthen floatability of copper ore and recover its fine particles.When the grinding fi...
