The optimal process flowsheet is selected after analysing the results of a detailed testwork program which evaluates the relative merits of each method. Another factor that contributes to the complexity of processing gold ores is the presence of adsorptionactive substances that trap dissolved gold and carry it with the tailings, 'pregrobbing'.

Mineral Processing. Molybdenum (moly) is often produced as a byproduct of copper mining. Copper is used for electronics, construction, and metal alloys. Moly is mostly used to make metal alloys, and as a catalyst. As markets need copper and moly, their ores are separated, concentrated, and sold separately.

HighConsistency System. Figure 6 shows a process flowsheet for a highconsistency oxygen delignification system. Typically, a press is used to raise the feed consistency to about 25–30%. Fresh caustic or oxidized white liquor, along with the magnesium protector, is added to the pulp at the discharge of the press.

Zinc smelting. Zinc smelting is the process of converting zinc concentrates ( ores that contain zinc) into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals, iron, because in contrast, zinc has a low boiling point. At temperatures typically used for smelting metals,...

Figure 2: Overview of a typical beneficiation process at a concentrator Sulfidic copper ores are too dilute for direct smelting. Smelting these materials would require too much energy and very large furnace capacities. The copper ore coming from the mine ( – 1 % Cu) must be concentrated by beneficiation.
