Flotation of Gold and Gold-Bearing Ores - ScienceDirect

01-01-2016  Copper–Gold Ores. Copper–gold ores are significant contributors to the overall world gold production. Flotation is the principal process for preconcentration of the copper–gold minerals for subsequent smelting treatment. Gold recovery, although important, is not always considered when optimizing the copper circuit.

Gold Flotation - 911 Metallurgist

13-07-2016  Finely divided metallic gold in milling ores floats readily, and a high-grade concentrate can be made by flotation if no interfering slime or gangue is present. Any good collector may be used for the flotation of gold, but organic collectors of the xanthate type produce a cleaner, higher grade concentrate than coal tar-cresote oils.

How to Process Copper Lead Zinc Ore with Gold and

27-04-2016  A complex sulphide ore of this type requires a high degree of selectivity in the flotation process. The lead and copper must be removed in bulk as a mixed concentrate and then the zinc floated as a separate concentrate because of marketing requirements. A further separation of the lead-copper into their respective products by flotation is often economically advantageous if the crude ore contains 0.8% copper

Metal production was increased to twenty-four metallic and nineteen non­ metallic minerals by the mid-twentieth century. Flo­ tation can be used in processing metallic orcs (e.g., copper, lead, zinc, gold, silver) or non-metallic ores

Copper-Cobalt ores - Danafloat

Copper-Cobalt ores. Various cobalt bearing minerals have economic significance including cobaltite (CoAsS). carrollite (Cu (Co.Ni)2S4), and linnaeite (Co3S4). These are often associated with copper minerals and pyrite and pyrrhotite iron sulphides. Two different flotation separation strategies are used.
