In terms of alluvial gold in South Africa, it is commonly associated with magnetite ,ilmenite, rutile, zirconium quartz, hematite, ferrochrome, iridium, cinnabar, tungsten, manganese, tin, diamond, corundum, calcite and other heavy minerals with its content being 1-3ktg/m3 as well as gravel, cobble and soil.3-10g/t in grade and 0. Also, consideration should be given to comprehensively recovering other heavy minerals by combined use of gravity, flotation, and amalgamation processes to separate gold from heavy minerals.Alluvial gold, also called placer gold, contains a number of heavy minerals in addition to gold. Therefore, in the mining process of alluvial gold, efforts should be made to conduct crushing, screening and desliming operations in the period of separation.2-2mm in size. Normally, placer gold in South Africa often occurs in granular, flaky, branched and needle shapes with 0.
