Gold ore is obtained from a variety of ores. Most people think a lot of gold comes from nuggets. But the truth is that very little comes from actual gold nuggets. Practically all newly mined gold comes from ores and gold quartz mined from the natural rock ore that carries gold in tiny, even microscopic particles.
3 Ways to Identify Gold in Quartz wikiHow
Sep 06, 2019 It nestles in the veins (lines) or cracks in quartz and will appear as small particles or scales. In some cases you may be able to see small masses of gold within quartz but much of it is invisible to the naked eye. Other minerals may look like gold in quartz, especially chalco pyrite, also aptly known as “fool’s gold”.

Adhesion of microorganism cells and jarosite particles on
Jan 01, 1999 The saturation adsorption densities was obtained for gold refractory ore. It can suggest a high affinity of dextrin to the surface of ore particles. For quartz the adsorption isotherm is not of the high affinity type and indicates weak interaction. Adhesion of jarosite particles on the ore particles is presented at Fig. 2.
Gold extraction
High-grade gold ore from a quartz vein near Alma, Colorado. The appearance is typical of very good gold-quartz ore. A "refractory" gold ore is an ore that has ultra fine gold particles disseminated throughout its gold occluded minerals. These ores are naturally resistant to recovery by standard cyanidation and carbon adsorption processes.
