Many chemical companies try to implement polymers in flotation (natural polymers, biopolymers, etc.). This is a traditional flotation reagents for some ores. SOLUTION 2. The use of polymers for activating copper ores and gold in flotation Increase extraction and content of copper and gold in the mineral concentrate using polymers! This is possible!
Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper. The ores typically contain low percentages of copper and have to be concentrated before refining (, via froth flotation). Figure 1: Chalcopyrite extracted from Zacatecas, Mexico.

Copper can be extracted from its ore by: Underground: sinking a vertical shaft into the Earth to an appropriate depth and driving horizontal tunnels into the ore. Open pit: 90% of ore is mined by this method. Ores near the surface can be quarried after removal of the surface layers. The ore is treated with dilute sulfuric acid.

Nov 28, 2016· Today we're using a centrifuge to concentrate our gold ore. We crushed the ore in a Jaw Crusher, which reduces the ore down to about 3/8" size, from .
An ore mineral is a mineral containing valuable metal(s). Ore minerals are commonly part of three groups: •Oxides such as Haematite or Chromite. •Sulphides such as Galena or Chalcopyrite. •Native (an element existing in its own right) such as gold.
To understand the ore matrix (elemental makeup) is the first step to proving out the most efficient recovery circuit; from classification of head ore, to concentration and achieving a smelting grade product.
Gold Gravity Concentration. The German system of coarse crushing, sizing by means of screens, and concentrating on jigs, is not, as a rule, applicable to gold ores proper, although much used on auriferous lead, zinc, and copper ores. This system will not be described here, where only the methods in use for the treatment of battery sands,...
The value of crude ore by perfect concentration is then for the lead concentrate and for the zinc, or a total of per ton of crude ore. By formula .

Concentrating the ore The ore is crushed, ground and then enriched (concentrated) by Froth Flotation . The powdered ore is mixed with a special paraffin oil which .
Mining and concentrating Uranium ores occur in deposits that are both nearsurface and very deep (, 300 to 1,200 metres, or 1,000 to 4,000 feet). The deep ores .

Copper extraction. As in all mining operations, the ore must usually be beneficiated (concentrated). The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper minerals (such as chalcopyrite ), the ore is crushed and ground to liberate the valuable minerals from the waste ('gangue') minerals.
Gold and silver are obtained from a variety of ores, in some of which the gold predominates, in others silver is the primary value, while in still a third class these two metals may be mixed with the base metals, such as lead, copper, zinc, and iron.
Concentration of ore Unwanted rocks, sand and grit from the mineral ore are called gangue or matrix. These have to be removed so that the mineral ore is concentrated with higher percentage of metal.
Liquation is a method for concentrating ores, which have a lower melting point than the impurities. The ores of antimony are concentrated by this method. The powdered ore is .
