Extraction of gold using cyanide Gold is found in very low concentrations in the ore from which it is mined. To collect the gold from the ore it needs to be separated from the other minerals in the ore. To do this the gold needs to be made into a soluble form so that it can be separated from the other minerals as gold is insoluble.

Of all the methods of extracting gold & processing it from its ore, I used a few to evaluate two principal flowsheets in this case study. The flowsheets utilized operations that involved flotation, cyanidation and gravity concentration. Tests that mirror each of these unit operations were utilized to evaluate the principal flowsheets. This page offers a comparative review of gold recovery ...

Recent work in treating a variety of refractory gold concentrates under optimum conditions (2251C, NaCl 10–20 g/L, 2–6 h O2 at 700 kPa) achieved gold extractions of the order of 90–96% compared with direct cyanidation where gold extraction was less than 20% (Ferron et al., 2003).

Cyanide Chemistry & Gold Extraction. The results of these studies, made on a large variety of ores, was to show in all cases a partial extraction of gold. This extraction varied from 20 per cent, to 95 per cent. While it was always easy to make a partial extraction of the gold, it proved difficult, and in many cases impossible, to get anything ...
Extraction is a process in which one or more components are separated selectively from a liquid or solid mixture, the feed (Phase 1), by means of a liquid immiscible solvent (Phase 2). The transfer of the components from the feed to the solvent is controlled by the solubility behavior
A few elements like carbon, sulphur, gold and noble gases, occur in free state while others in combined forms in the earth's crust. The extraction and isolation of an element from its combined form involves various principles of chemistry. A particular element may occur in a .
gold miners Small-scale miners Some SSM communities continue to practice the same method of gold extraction developed by their forefathers, whereas other groups are innovative and try to improve working techniques to increase gold recovery rates. An excellent example of this is a group of SSM in the Benguet province in the Philippines.
