Gold can be concentrated and recovered by applying different gold refining process methods and the final product has variable quality. In this way, it is necessary to have a better marketable product so that the incomes can be improved.

Specifically, at gold processing plant, example gold processing plant at Goldfields Ghana LimitedTarkwa Mine in Ghana, the term reagent is used to describe material input that the plant needs to generate physical and chemical reactions that lead to the extraction of the mineral of interest.

However, there are some limitations in flotation, such as ores with gold particles larger than mm or pure quartz gold ores without metal sulfides, which are difficult to deal with by flotation separation alone. This paper introduces commonly used reagents and the flotation process of gold and silver ore for you. You may interest in 1.

Flotation Reagents For Mineral Processing. Kemcore supplies various mineral processing reagents used in the flotation process. We supply reagent schemes which consist of collectors, depressants, activators, pH regulators, Frothers. Our flotation reagents are suitable for many metals, particularly copper, lead, zinc, silver, gold, and nickel.

The costeffective process replaces cyanide with a safer, less hazardous chemical reagent, thiosulphate. This inorganic compound helps dissolve fine gold out of ores into a solution, which can then be recovered through further processing.

Cyanide, mercuryfree gold process a reality FIRST gold has been produced using a nontoxic chemical process designed to provide an alternative to using cyanide and mercury to extract the yellow metal.
