What is the most suitable process for quartz vein gold ore?

2020-3-6  A typical quartz vein gold ore was selected as the sample ore. The main useful mineral is gold, followed by a small amount of silver and pyrite, and the main gangue mineral is quartz. The results of chemical multi-element analysis of raw quartz vein gold (Table 1) and phase analysis results (Table 2) are shown in the following tables.

2007-4-5  Quartz Veins. Quartz veins are numerous in the schists of the Littleton formation. They range up to about two feet in thickness and many tens of feet in length. On outcrop surface they may appear as simple, clean-cut bands or they may grade into highly irregular and anastomosing vein-complexes. Some are sharp, straight veins whereas others are ...

2019-1-18  Quartz veins are characterized by several varieties of quartz, such as colorless quartz (rock crystal), smoky quartz, rose quartz, amethyst, citrine and milky quartz. The observed heterogeneity of quartz type is a result of variation of the trace element contents and volume of gas and fluid inclusions (Götze and Möckel 2012 ).

1993-7-1  Chemical activity, pH and temperature gradients may result from alteration zoning around the quartz vein as the fluid flows away from the vein into the wall-rock (Rose and Burt, 1979). If fluid is channelled into sepa- rate structural-zones or wall-rock types, differ- ent streams of fluid tend to evolve indepen- dently (Fig. 11 ).

Fluid inclusions (FIs) in minerals are known to contain a variety of different liquids, gases, and solids. The fluids get trapped during mineral growth and can preserve the original mineral-forming fluid or fluids of later events. A new analytical technique developed by Mulder et al. (2013) [1] allows to measure trace gases in FIs. For the measurements, grains of 3-5 mm diameter are ground in ...
