· Gold is typically extracted using various methods, including placer mining, hydraulic mining, and heap leaching. Once extracted, gold ore is often processed through crushing, grinding, and chemical treatments such as cyanidation to separate the gold from the ore matrix. In contrast, platinum mining involves processes such as crushing, milling
