Open-pit Mining: Open-pit mining is a method used to extract gold from large, near-surface deposits. It involves the removal of overlying soil, rock, and vegetation to expose the gold-bearing ore. Once the ore is exposed, it is drilled, blasted, and transported to a processing plant for further extraction.

Gold ore can generate in the Overworld in the form of ore features. Gold ore attempts to generate in two batches. The first batch generates 4 times per chunk in blobs of 0—13 blocks, from levels -64 to 32. It is most likely to be found around layer -16, becoming less common toward either end of the range.

Carbon (from Latin carbo 'coal') is a chemical element; it has symbol C and atomic number 6. It is nonmetallic and tetravalent—meaning that its atoms are able to form up to four covalent bonds due to its valence shell exhibiting 4 electrons. It belongs to group 14 of the periodic table. Carbon makes up about 0.025 percent of Earth's crust.
Thiosulfate leaching is considered to be a promising method for carbonaceous gold ore treatment because of low affinity of gold thiosulfate complex to activated carbon (Gallagher et al., 1990, Aylmore et al., 2014). Many reports on the use of thiosulfate solutions to extract gold from carbonaceous ores have been published.
The CIP ( Carbon In Pulp) process is suitable for treating oxidized gold ore with low sulfur and mud content. It is unsuitable for the gold ore with high-grade silver as well. Generally, the proportion of gold and silver should not exceed 1:5. The best conditions for Carbon In Pulp process in China: PH=10-12, sodium cyanide concentration is not ...
