2 天前 The slurry that remains after this process has a very fine particle size. Typically, 80% of the ore particles are less than 70 microns in size (about the same consistency as fine beach sand). Such a fine particle size is required for gold liberation – the size required for the cyanide to be able to ‘see’ the gold in the leaching process.

Processes of gold ore separation - Prominer (Shanghai)

Among them, gravity separation is a commonly used process in placer gold mines, flotation is mostly used in rock gold mines, and cyanidation is suitable for refractory gold ores

What are Methods of Cyanidation Gold Extraction Process
2022-6-21 The basic process of gold extraction by resin pulp method is: #1. Adsorption: When the gold-containing cyanide solution passes through the exchange resin column, an ion exchange reaction occurs, and gold is adsorbed on the resin. #2. Desorption: The gold on the resin is desorbed into the solution with a desorbent.
