Gold-Silver Separation. The initial step is to weight the Dore metal. Since silver is leached by nitric acid and gold no, the next step is to attack the Dore metal with a hot diluted solution of nitric acid. The acid dissolves the silver and leaves the gold that has to be rinsed, dry, and weight on a scale of high sensibility such as 0.001 mg.

7. Spin, rinse, & dry – – use an automated SRD for best results and sparkling clean wafers. Notes: Exact proportions of SC-1 and SC-2 solutions vary from lab to lab. (Often passionately!) Standard wafer clean is used for any new wafer prior to any processing. RT = Room Temperature, i.e. non-critical, but around 21 C. 10:1 BOE is usually

For perfect buds, cure for 6-8 weeks. Open up the jars every day for 30-45 minutes to get the fresh air in (this process is also known as burping) Keep the jars out of direct light, as it can breakdown cannabinoids. Once you're done with drying and curing, your bud will go from 80% moisture to around 10-15% if you did everything right.

The dry powders can be compressed using a conventional tablet machine or, more usually, a large heavy-duty rotary press can be used. This process is often known as 'slugging', the compact made in the process (typically 25 mm diameter by about 10–15 mm thick) being termed a 'slug'. A hammer mill is suitable for breaking the compacts.

It has now become almost an essential unit operation in any gold processing plant to assess the gravity recoverable gold content in the ore as well as to recover fine free gold from the grinding circuit. Knelson Concentrator (KC) first introduced to the hard rock milling industry there-by providing gold recovery by handling a maximum feed size ...

Dry washing, by its very nature, is an extremely dusty process and the operator is urged to stay up wind as much as possible and even to consider wearing a dust mask when dust cannot be avoided. With both types, the gold gravitates down to the canvas and is held by the riffles, which are set up in the direction opposite of a normal wet sluice.

The original method of dry granulation employed a heavy duty tablet press to compact the dry powder. The compacting process in this case is known as slugging and the compacted material was therefore in the form of "slugs" - typically 25 mm in diameter and 10-15 mm thick. A hammer mill is ideal for breaking up the slugs to create granules.

The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon. CIL stands for carbon-in-leach. This is a gold extraction process called cyanidation where carbon is added to the leach tanks (or reaction vessel) so that leaching and adsorption take place in the same tanks.
