Easy Ways to Extract Gold from a Rock (with Pictures ...

The safest way to extract gold from rocks at home is to crush the rocks. However, you might use mercury to extract the gold if you're able to obtain some, though this is dangerous. While both mercury and cyanide can be used to extract gold from rock, it's hazardous to both your health and the environment to use them.

New approaches for extracting and recovering metals from ...

Mineral tailings from two copper mines were bioleached under different conditions. • Greatest copper extraction was achieved at extremely low pH, at 45 °C and under oxidative/reductive conditions.. Copper present in tailings PLS was selectively precipitated as CuS by biogenic H 2 S.. Microbial communities were dominated by Sb. thermosulfidooxidans and Acidithiobacillus spp.

Extraction Of Copper | Mining, Concentration, Smelting ...

The copper extracted from this process is mixed with the slag and is called Matte Copper due to its texture and appearance. This mainly consists of Cu2S which is reduced to pure metal by blasting Matte Copper with air. Cu 2 S+O 2 → 2Cu+SO 2. The sulphur dioxide escapes the copper and this causes bubbles to appear and burst as SO2 leaves. This ...
