Method of making an ore concentrator, and concentrator

The thus-formed bowl-shaped concentrating pad assembly, which is another aspect of the invention, is then secured in an ore concentrating apparatus. Very importantly, the flexible cement and the stretchable backing sheet, permit the pad to be vacuum-moved into the bowl in a practical manner, and without effecting cracking of any adhesive.

What is Concentration of Ore? Definition, Physical

Apr 10, 2019 The ore concentration is defined as the chemical process of eliminating impurities like sand, rocks, silt, grit etc. from the ore to extract the metals. In simple words, the concentration of ore is the method of separating ore from the gangue, as the gangue or matrix particles are the valueless substances that are of no use.

Concentration of ore @ Chemistry Dictionary & Glossary

Oct 20, 2018 Concentration of ores is important industrial processes and is the first steps to the extraction of the metals. Normally, the ore is concentrated by separating it from the clay body in which it occurs either by gravity, sedimentation, or by a floatation process, before the extraction of the metal from the ore is started.

US4008152A Metal separating process and apparatus

Heavy metals such as gold, silver platinum, copper, etc., in the free state, are separated from their ore by applying water and the ore in finely divided form to at least three rotating, inclined, spiral grooved discs driven from a common shaft. The grooves are closely spaced and with declining pitch from the periphery to an annulus at the center of the disc.

Copper extraction Wikipedia

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).

1 Froth Flotation Fundamental Principles

(a) From Table 1, the Ratio of Concentration can be calculated as F/C = 100/10 = 10. If only assays are available, the ratio of concentration equals (20 0.1)/(2.09 0.1) = 10 So, for each 10 tons of feed, the plant would produce 1 ton of concentrate. (b) Using the example data from Table 1, the % Cu recovery calculated from weights and
