Froth Flotation Native Copper Flotation

Copper extractionWikipedia

Supergene sulfide ores rich in native copper minerals are refractory to treatment with sulfuric acid leaching on all practicable time scales, and the dense metal particles do not react with froth flotation media. Typically, if native copper is a minor part of a supergene profile it will not be recovered and will report to the tailings.

Copper FlotationMineral Processing & Metallurgy

May 16, 2016· The flotation of native copper ores is nearly always preceded by gravity concentration in jigs and tables not only because the combined process is more economical as regards costs, but also because the copper often occurs as large grains which flatten out during grinding and cannot be broken to a size small enough for flotation.

Chapter 6 Copper Production Technology

As early as 6000 B. C., native copper–the pure metal—was foundas reddish stones in the Med- iterranean area and hammered into utensils, weapons, and tools. Around 5000 B. C., artisans discovered that heat made copper more malle-able. Casting and smelting of copper began around 4000-3500 B.C. (see figure 6-2). About

A platinum flotation circuit. In a process called flotation separation, air bubbles are blown through the mixture and carry platinum particles to the surface of the bath. The platinum-rich froth is skimmed from the bath and allowed to dry into a concentrated powder. One ton of dried powder may contain between 3 and 30 ounces (85 to 850 grams,

A History of Copper Prices | Winton

In the late 18 th and early 19 th centuries, the primary demand for copper was for sheathing the bottoms of boats, to protect against shipworm and seaweed. Copper-bottomed vessels were both faster and required less docking time than their untreated counterparts. The Royal Navy’s decision to re-hull their entire fleet in the 1780s gave Britain a strategic advantage during the Napoleonic Wars,
