free-milling gold的意思|示意

'

Free-milling gold is a term used to describe a type of gold that can be extracted from its ore without the need for chemical processes. In most cases, the ore is crushed and the gold is extracted with a typical gold panning technique.

It is important to note that free-milling gold is not a guarantee of gold quality. Gold ore with free-milling capabilities can also contain other minerals or metals that can contaminate the result. Therefore, it is important to test the ore prior to extraction.

Once the gold-containing ore is placed in a water bath, the gold will begin to settle at the bottom. This is because gold is heavier than the other components in the ore. The heavier the gold, the faster it will settle at the bottom. The panning method involves using a pan to separate the gold from the other materials.

Once the gold has been separated, it can then be melted in a furnace, or smelted, to make a cast bar. The cast bar can then be processed into coins or other precious metals.

Free-milling gold is a common way for miners to extract gold from ore. It is an economical option, as it does not require any specialized tools or chemical processes. However, it is important to note that it is not a guarantee of gold quality. It is best to always test the ore prior to extraction, to be sure that the desired result is achieved.
