Gold is often found with quartz because quartz is also a "mineral fluid" of the earth that solidifies, just like gold does. Due to this fact, their chemical compositions are complementary and almost always found together. In addition to that, the structure and formation of quartz is very accommodating for the soft nature of gold.

Abstract: The gold deposit at Ashanti occurs in the Proterozoic Birimian formation of Ghana. Two main ore types mined from the deposit are gold-bearing quartz veins, and gold-sulfide disseminations in metasediments and metavolcanics.
The use of thiosulfate to extract gold from refractory ores is promising because of its non-toxicity and high selectivity. Sulfide minerals (i.e., pyrite, arsenopyrite, chalcopyrite), major gold carriers in refractory gold ores, however, hinder gold extraction due to the high consumption of a lixiviant. In this study, a new method to improve gold …

In India, there are several manufacturers of gold ore pulverizers that cater to the needs of the mining industry. These manufacturers specialize in designing and manufacturing machinery that efficiently crushes and grinds gold ore into finer particles, facilitating the extraction of gold. One prominent manufacturer in India is Prominer (Shanghai)...
In the mid-19th century, gold rushes in California and Australia signified a striking relationship between gold and quartz, as the precious metal was frequently mined from quartz veins.
Quartz gold ore is found in large veins of quartz, most commonly rose quartz and rainbow quartz. If the gold is on the surface of the rock it'll look like shiny yellow flecks or veins of gold.
The methods of extracting gold from quartz vein ore, sulfide ore, polymetallic gold-bearing ore, gravity separation, flotation, and cyanidation can all …
The Au enrichment is related to the formation of a quartz–sulfide vein system and a progressive evolution of ore-forming fluids with decreasing temperature, from Sb- to As-rich to final precipitation of native gold from silica and Au-bearing low-temperature hydrothermal colloidal solutions.
The various types, textures, and compositional zoning of pyrite in the gold-bearing saddle reefs, quartz veins, and surrounding sedimentary rocks provide new information on the potential source ...
The large, andesite-hosted quartz vein system at Waihi contains a major epithermal Au-Ag deposit (total production of 6.4 Moz Au and 39.9 Moz Ag, Ag:Au = …
The Kowary deposit largely differs by the presence of large quantities of magnetite-bearing skarn and late stage Umineralization but has a similar polymetallic sulfide paragenesis. ...
The Sakatti Ni-Cu-platinum-group element deposit is situated in northern Finland and comprises massive, disseminated, and vein sulfide mineralization. A stockwork is formed by chalcopyrite-rich sulfide veins, which contain exceptionally high platinum-group elements and Au grades. The mineralogy and geochemistry of this …
These deposits consist of Archean through Tertiary quartz veins, primarily mined for their gold content, that generally contain no more t han 2 to 3 volume percent sulfide …
The "Mother Lode" of gold in California is a region crisscrossed by many such quartz-and-gold-filled hydrothermal veins. Nearly all hydrothermal quartz veins everywhere contain some amount of gold. To find the gold, first find the quartz.
This paper aims to resolve two main problems related to the formation of quartz veins: (1) the predominance of quartz veins at shallow crustal levels and not …
The gold mineralization can be categorized into gold associated with carbonate-rich zones hosted within dilated quartz veins, which contain significant amounts of sulfides, such as pyrite, pyrrhotite, sphalerite and galena, and discontinuous, strike-restricted quartz–ankerite–sulfide veins.
In the experiment, the sulfide refractory gold ore (5 g) was loaded into quartz porcelain boat and a desired amount of air was introduced when the desired temperature was reached.
Galena forms in low- and medium-temperature ore veins, along with other sulfide minerals, carbonate minerals, and quartz. These can be found in igneous or sedimentary rocks. It often contains silver as an impurity, and silver is an important byproduct of the lead industry.
