metal ores, the gold is floated from the base metal tailings. The flotation of gold-bearing ores is classified according to ore type (i.e. gold ore, gold. copper ore, gold antimony ores, etc.), because the flotation methods used for the recovery. of gold from different ores is vastly different.
Jul 23, 2014· Since its discovery, froth flotation has been a major component for the processing of sulfide-rich ores, including copper, coal, and refractory gold. In gold mining, froth flotation is used to separate gold from gangue by utilizing gold’s hydrophobicity. First, refractory gold ore is ground as finely as possible usually so the individual
The ores from which silver and gold are recoverable by flotation divide themselves naturally into two general processing classes: ores in which the valuable minerals are those of the base metals, the precious metals being incidental constituents, and ores in which the gold and silver are of primary importance, the base-metal minerals, if present, being of little or no value. The first class

Gold processing, preparation of the ore for use in various products.. For thousands of years the word gold has connoted something of beauty or value. These images are derived from two properties of gold, its colour and its chemical stability.The colour of gold is due to the electronic structure of the gold atom, which absorbs electromagnetic radiation with wavelengths less than 5600 angstroms
Gold recovery chemicals is the reagent that used to extract gold, which is one of necessary element in gold processing plant. The commonly used gold recovery chemicals can be mainly divided into three types: flotation chemicals, heap leaching chemicals and cyanidation leaching (CIL, CIP) chemicals.
Mines are faced with numerous challenges, such as falling raw material prices, declining metal grades in the ores and higher energy prices. Especially because ore processing is particularly energy-intensive, the industry is again focusing on the saving of energy. This report shows what are the key energy saving considerations in the copper and gold mining sectors.
