How to Use Bleach on Gold Ore to Remove Gold
Apr 24, 2017This was the first commercial method used for gold extraction. Place the ore into the mortar and grind it to the size of sand grains. Put the ore grains into a plastic bowl. Add the 35-percent hydrochloric acid to the sodium hypochlorite bleach into a flask or beaker, in a two-to-one ratio of acid to bleach. Ensure that the liquid mixture is at

What are the main methods of mining?
There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.

Extraction Of Metals
Dec 06, 2019Ores are collection of minerals containing one or more metals [4] [5]. These metals are economically and conveniently extracted from these ores by following certain extraction techniques. The reason behind presence of metals in form of ores and minerals is that, most of metals being highly reactive, cannot exist in free form [6].
