The gold CIP (Carbon-in-Pulp) processing is widely used to extract gold from ore. It mainly involves using activated carbon to adsorb gold from a cyanide solution, then eluting and regenerating the carbon for reuse. It is mainly suitable for beneficiating gold-containing oxidized ore with high slime content and containing carbon ore.

About Placer Gold. Placer gold refers to the gold formed by the rock gold in the mountain washed by the river and separated from the quartz vein. Because this kind of gold is as fine as sand, it is called placer gold. Gold mining is divided into rock cave digging and panning in rivers and streams containing gold. For example, gold taken from mines is called gold or melon seed gold, and …
These technologies are the basic technologies for mineral processing plants to extract gold from different types and grades of gold deposits. Of course, there are other Mineral processing technology. Reasonable gold ore beneficiation technology needs to be determined based on the type, form and other factors of the ore.
be exposed. Mohammadi et al. investigated ammoniacal thiosulfate leaching of refractory oxide gold ore, and they obtained maximum gold extraction of 55% (Mohammadi et al., 2017). Shen et al. had researched the direct thiosulfate leaching of gold from refractory ore, and they achieved gold recovery of only 70% (Shen et al., 2013).
In the tenth century, copper was produced by the bile copper method. In 1887, gold and silver were leached from ore by cyanidation, which opened up the way of modern chemical mineral processing. ... Besides treating refractory raw ore, chemical mineral processing can also effectively treat middling, tailings, coarse concentrate, mixed ...

Geology, deposit types, and ore minerals. There are more than 200 minerals that contain REE. 7,8 The most common rare-earth minerals are monazite and bastnäsite (Figure 1a–b and Table II).Monazite exists as a group of arsenates, phosphates, and silicates, but the primary REE-bearing monazite is a complex phosphate. 5 Bastnäsite, also known as …
The presence of gold telluride minerals may render an ore refractory, the extent of this depends on the telluride mineral present and the mineralogical association [3]. Gold, silver, and gold/silver-telluride minerals in ores dissolve more slowly than native gold in cyanide solutions, which results in less efficient gold extraction [4].
