Additionally, the A2 mill plant has another smaller grinding line with two ball mills (13×18 ft, 1305 kW). Each grinding circuit is followed by a rougher froth flotation circuit. The rougher concentrate from the three mills goes through a single cleaner, scavenger, re-cleaner, and re-scavenger circuit that produces a copper-molybdenum concentrate.

Copper Ore Grinding Machine. The content of copper ore flotation and ease of iron sulfide ore closely. According to the number of sulfide copper ore iron sulfide content divided into two categories, one is dense massive copper ore, one is disseminated copper ore. The former is characterized by a high content of pyrite ore, sometimes up to 80%,
