The lower adsorption of Cu (CN) 3 2 − and Cu (CN) 4 3 − onto activated carbon accounts for the use of high cyanide concentrations to improve the selectivity of gold over copper when this adsorbent is used for gold recovery. In contrast the use of low cyanide concentrations is used to promote selectivity and higher adsorption of Cu (CN) 2 …
Ores of sufficient sulfur and carbon content can be treated autothermally. Some ores with low sulfur and carbon contents call for additional heating in order to maintain the roasting reaction. Since the gold content of most ores is low, large amounts need to be treated in order to ensure attractive economics. The goals of the roasting …

2.1 Microwave pre- treatment of refractory gold ores . Most of refractory gold occurs within sulphide minerals such as FeS 2 and FeAsS and are treated by roasting, pressure leaching or bacterial leaching to render the gold amenable to recovery by subsequent treatment techniques (Haque, 1987).
gold ores can be classified into 11 types (Table 1). Some metallurgical implications to these gold ore types are summarised below: Placers, quartz vein gold ores and oxidized ores: Generally, placers, quartz vein gold ores and oxidized ores are free-milling and gold can be recovered by gravity and/or direct cyanide leaching.
In Minecraft 1.18 update, gold ores start appearing at Y level 32 and generate down to Y level -64. When it comes to initial generation, it generates in a spread manner and peaks around Y level -16.

Original sulfide content is typically 2–3% pyrite, and the gold is often enclosed in the pyrite. Oxidized ores yield 65–85% recovery but may have to be crushed to below 12 mm (½″), although some ores are successfully leached at run-of-mine sizes. Unoxidized ores yield 45–55% gold recovery and nearly always need crushing. 2.1.3.
