Beneficiation of Gold and Silver Ores | SpringerLink
Flotation of ore at a top-size of 3 mm, followed by gravity concentration of the flotation tailings, has been applied previously in South Africa to treat Witwatersrand gold ores resulting in the production of a 40% mass pull at an overall gold recovery of 98% (Lloyd, 1979). Coarse particle flotation of particle ranging from 3 to 5 mm is common ...

What Does Gold Ore Look Like? | Sciencing
Updated April 25, 2017. By Christina Hadley. To the untrained eye, gold ore may look like rock with copper tones flowing within it. However, professional prospectors know how to recognize gold ore within a multitude of minerals. Recognizing the look and the location of gold ore is easier if you know how to find lode and placer deposits.

2. Granite. Granite is a complex stone, which is why it comes in so many colors. It's loosely defined as a coarse-grained, quartz-rich, intrusive igneous rock. Auriferous granite often contains gold-bearing quartz veins as well, and these veins are generally sought out first by miners due to their higher gold content.

Among such rocks are granite, aplite, gneiss, eurite, quartz-trachyte, syenite, andesite, basalt, diorite, gabbro, diabase, schists, porphyry and slate. These deposits seldom pay to work and in that case can hardly be called gold ores. J. E. Spurr writes—"Native gold has been found in both basic and acid rocks.
