What Makes a World-class Gold Deposit? (Updated 2023)

Grade refers to the proportion of gold contained in ore and is represented in grams per metric ton (g/t). Generally, companies want With ores of higher gold content (i.e., greater than 20 grams of gold per ton of ore), cyanidation is accomplished by vat leaching, which involves holding a slurry of ore and solvent for several hours in large tanks Gold processing Mining, Concentrating, Refining

Making the grade: understanding exploration results

GOLD: It is usually reported in grams per tonne (or g/t), although sometimes, in the US, it is in oz/ton. A gram of gold is worth about $25, so 2 grams or better would be viewed as high-grade for bulk tonnage mining. Therefore, classification by screening can improve the gold recovery, which is also applicable for all gravity concentration processes. Shaking tables can process up to 2 tonnes per hour (tph) of Free Full-Text Gravity Concentration in Artisanal Gold
