Copper sulphide liberation for the Lab Composite measured about 48 percent when measured in two dimensions which would be considered slightly low for good rougher circuit recovery. Typically liberation values of about 50 to 55 percent are targeted in the primary grind for good sulphide rougher circuit performance. Unliberated copper sulphides .

Polymetallic Flotation Equipment Complete Ore Process

Polymetallic Flotation Equipment Complete Ore Process

This ore processing plant is for the flotation of 2 base metals CuPbZnCoNietc. which may or may not contain precious metals. These ore deposits are called polymetallic by geologists and metallurgists. This system allows you to recovery by way of differential or sequential flotatio the sulphide metals in 2 separate concentrates. Examples include Copper Lead Zinc Cobalt Nickel .

Copper concentrators typically treat up to 100 000 t of ore per day. They are located directly at the mines to achieve low transport costs. The copper recovery efficiency is over 90 . About 95 of the ore input goes into the tailings which are stored in large dams near the mine and are used for water recycling to the flotation stages.

low zinc Zn ore was fed to the plant. Marketable copper concentrate at 91-95 recovery was produced utilizing a high-pH bulk sulphide rougher flotation and 2 cleaning stages. Because of increased levels of Zn of the ore body a CuZn separation circuit was initiated in early 2010 following an intensive laboratory test work program.

Tracking comminution energy and optimising grind size

The grind sizes in the primary-secondary-tertiary and regrind circuits and recoveries in the rougher-scavenger and cleaner blocks can be determined for an overall economic optimum. A concentrator can assess its energy cost performance by tracking specific energy use.
