Ore Processing Challenges in Gold Operation Grinding Circuits. By Scott Ferguson 06.16.2020. Continuous control of the final grinding product size is important to optimize gold liberation for gold milling operations. In addition, the live monitoring of the final product particle size leads to a maximum grinding circuit throughput.

Gold flotation. Flotation process is widely used for lode gold processing. In most cases, the flotation method has a good effect in sulfide-containing gold ore with high floatability. In addition, the flotation process is also used for polymetallic gold-bearing ores such as gold-copper, gold-lead, gold-copper-lead-zinc-sulfur ore.

crushing, followed by dump or heap leaching with cyanide. Gold recovery is usually around 80%, but can be as low as 60%. Recoveries can be improved to amenability of an ore to the cyanidation process are gold leach efficiency and cyanide consumption as a function of the fineness of grind and other leach conditions.

For most small-scale gold prospectors, crushing ore to determine the amount of free gold is the best method to determine gold content within an ore sample. Free gold can then be collected using traditional gravity based methods, which do not require the same level of permitting as the chemical methods used by commercial gold mines.

Blasting, crushing, and grinding are necessary to liberate the gold for recovery. Hard rock gold deposits have three sub-classes: free-milling, sulfide-associated and refractory. Free-Milling Gold. Gold ore is considered free-milling when it is easily liberated by grinding and separated from the other minerals.

In a typical pyrytic gold ore, the gold is encapsulated within an iron sulfide crystal structure. Highly oxidized ores generally do not respond well to flotation. Advantages of the flotation process are that gold values are generally liberated at a fairly coarse particle size (28 mesh) which means that ore grinding costs are minimized.
