Calaverite is a telluride mineral that's really special because it's packed with gold. It's not just a rock with a little bit of gold; it has a lot of it, making it pretty unique. In calaverite, gold isn't just a tiny part – it makes up about 42% of the mineral. This means that calaverite is almost half made of pure gold.
Increasing wash water to 3.5 tons of water per ton of solids, or a wash ratio of 1:1.1, raises recovery to about 95% (Table 2). Adding one stage (a four-thickener circuit) and …
Gold has always been prized and coveted from ancient civilizations to modern society. While the quest for this precious metal may have changed over time, one thing has remained constant – the need for efficient methods of extracting gold from ore. Extracting gold from ore is a complex process that requires precision and expertise.

50/100 F = 0.7507 = mechanical loss of cyanide per ton of ore. Dissolution during Washing. Some additional dissolving of gold and silver takes place during the washing of the ore pulp after agitation with cyanide solution, either in C.C.D. thickener series or in filters.
The recovery of dissolved gold from slime pulp in the cyanide process was first accomplished by intermittent decantation. This simple process consists in mixing with the pulp containing the values in solution, a solution of lower gold content, settling the mixture in a tank and decanting the clear supernatant fluid.
Mineral washing refers to the process of scrubbing the ore cemented by clay or containing a lot of mud by hydraulic or mechanical force, so that the ore is broken up, and the fine mud on the surface of the ore is washed and separated. Mineral washing process is often used to process clay iron ore, manganese ore, apatite ore and placer …
Read this blog to learn about ore washing and ore washing equipment. The term "washing" can be defined as "removing a substance by or as by the action of water". In a mineral processing sense, washing commonly refers to the removal of loosely attached particles — often fine clays — from the surface of more competent ore.
To test if a rock has gold, rubbing the rock and smelling it can be informative. Gold doesn't have a smell, but pyrite, often confused with gold, smells like rotten eggs due to its sulfur content. This method is easy and doesn't damage the rock, but it won't differentiate gold from mica, which also doesn't have an odor.

Scratch test Gold is a very soft element, so scratching it will leave marks. Use a knife to try and scratch the surface of your rock. If it's gold, you'll see scratches. Pyrite will be too hard to be affected, and mica will flake off when scratched. If you don't have a knife handy, scratch gold with a piece of copper (like a penny).
