Phytomining of gold: A review - ScienceDirect

Phytomining has potential to allow economic exploitation of low grade ores or mineralized soils that are too poor for conventional mining of metals. Gold is the most promising option for phytomining as its market value is increasing continuously.

Orogenic gold and geologic time: A global synthesis

Orogenic gold deposits have formed over more than 3 billion years of Earth's history, episodically during the Middle Archean to younger Precambrian, and continuously throughout the Phanerozoic. This class of gold deposit is characteristically associated with deformed and metamorphosed mid-crustal blocks, particularly in spatial association with major crustal structures.

The giant Kalgoorlie Gold Field revisited - ScienceDirect

2016-5-1  The refractory gold ore in pyrite and telluride minerals is roasted to liberate the gold. The Gold Field has been continuously studied since gold was discovered, with the first mineralogical reports (e.g. Card, 1898, Frecheville, 1898), geological map (Maitland and Campbell, 1902) and structural evaluation (McLaren, 1910) produced just a few years after discovery. However, despite over a century of

Heap Leaching of Gold and Silver Ores - ScienceDirect

2016-1-1  Gold recovery efficiency from operating heap leaches is typically ∼70%, although it can range from 50% to 90%. Silver recovery efficiency is typically ∼55%. Most gold heap leaches apply cyanide within a range of 200–600 mg/L NaCN. Silver-bearing ores should usually be leached with a cyanide level of 600–1000 mg/L NaCN.

Designing gold extraction processes: Performance

2017-8-1  In this study, nine attributes: Ore type, Gold ore grade, Gold distribution, Gold grain size, Sulfide present, Arsenic sulfide, Copper sulfide, Iron sulfide and Clay present were modelled. Gold mineral type, referring to the most general description of the ore, such as “ Free milling ” or “ Silver rich ”, and gold concentration, or Gold ore grade , were relatively straightforward to model into attributes.
