Froth Flotation (Sulphide & Oxide)
Hello recently, I am working on processing of a gold bearing mixed oxide-sulfide copper ore (Av. Cu; 0.80 & Av. Au; 0.2ppm). After some research and testing different methods, I found Controlled Potential Sulphidisation (CPS) Flotation as the most effective & practical method on similar ores (E.g., Kanmantoo, Australia & Kansanshi, Zambia).
Design, Modeling, Optimization and Control of Flotation Process
The efficiency of a flotation circuit operation relies on several factors that are pertinent to mineral nature and structure (variability of ore feed, particle size, complex mineralogy, and morphology) as well as the type of instrumentation and operational parameters (design parameters, reagents, quality of process water, air flow rate, and ...

Typical flow-sheets in flotation practice. Flotation enters into mill flow-sheets in two capacities, viz.: (1) as a method of treatment accessory to gravity concentration; (2) as the principal method of concentration. ... Thus in an ore containing both sulphide and oxide copper the recovery credited to the process should be based …
Copper Process Flowsheet Example
A simplified schematic drawing of copper flotation flowsheet. Run-of-mine open pit ore will be crushed in a gyratory crusher. The crushed ore will be processed by means of semi-autogenous and ball …
Copper Flotation
Because the copper in this type of ore usually assays only plus or minus 1% copper, the porphyry copper operations must be relatively large in order to be commercial. The flowsheet in this study illustrates a typical 3,000 ton per day operation. In general most operations of this type have two or more parallel grind…

Sequential Copper–Lead–Zinc Flotation
In these tests, a zinc flotation was also performed to measure the metallurgical performance of that metal. The flowsheet schematic and summary of test results. As shown in the summary tables, copper was, on average, 63% recovered into the copper concentrate grading 24% copper.
Flotation | Mineral Processing, Separation & Beneficiation
Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water. The flotation process was developed on a commercial scale early in the 20th century to
Cu/Mo Ores | Molycop
The standard flow sheet consists of bulk sulphide flotation of copper and molybdenite while depressing gangue and iron minerals in the rougher and cleaner circuits. Recovery of copper is by standard flotation reagents identified in the copper ore flotation description.

The Sarcheshmeh copper mine is a significant copper and molybdenum producer. Sampling of the Sarcheshmeh flotation circuit (in a six-month period) showed that a large share of waste of molybdenite ...
Implementation and practice of an integrated process to recover copper
An integrated process to recover copper from low-grade copper grade sulfide ore and acid wastewater (AMD) has been developed and applied. The process includes the operations of milling-flotation, heap bioleaching, SX-EW and copper sulfide precipitation. In the process, copper and valuable metals are efficiently recovered.

60 Centuries of Copper: The Flotation Process
Only the flotation process mentioned above could make this practicable; and even so, it requires large companies with huge plants, continuous working and immense capital. This explains why, in order to smelt 4 million tons of new copper in 1963, nearly 400 million tons of ore had to be handled and treated in various ways.
