and commissioned in November 2008. During the initial stages of sulphide operation, high copper (Cu)-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
The zinc reporting to the bulk flotation tails feeds the zinc circuit which is operated as previously described in the lead-zinc flotation section. Which flotation scheme used in the differential copper-lead bulk concentrate separation is generally and often dependent upon which mineral has the greater mass in the bulk concentrate.
Many of the porphyry copper deposits contain molybdenite and some also contain lead and zinc minerals. Even though these minerals occur in relatively small amounts they can often be economically recovered as by-products for the expense of mining, crushing, and grinding is absorbed in recovery of the copper.

The copper tails feed the lead circuit where lime is added to the first conditioner tank, and zinc sulphate, sodium cyanide, and frother are then added into the second conditioner. The lead rougher concentrate is then cleaned generating a concentrate grading at 0.6% Cu, 71% Pb, 3.7% Zn and 800 g/t Ag, at 90% Pb recovery.
The copper-lead-zinc ores have an origin similar to copper-zinc and lead-zinc ores, the exception being those ores that contain copper, lead and zinc as the principal economic minerals. In addition, some of these ores contain significant amounts of precious metals and, more rarely, cobalt and nickel.

discovered that heat made copper more malle-able. Casting and smelting of copper began around 4000-3500 B.C. (see figure 6-2). About 2500 B. C., copper was combined with tin to make bronze—an alloy that allowed stronger weapons and tools. Brass, an alloy of copper and zinc, probably was not developed until 300 A.D.
