Result Of The Grinding Of Quartz Vein
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.

Quartz veins can have a variety of differing structures depending on the environment of formation and the host rock. The most common type of quartz vein is the simple filled vein, which could have a thickness ranging from a small fraction of an inch up to monster veins of quartz with a thickness of 20 to 30 feet and sometimes even more.

Understanding Low Sulphidation (LS) Epithermal Deposits
2018-2-2 The uppermost parts of epithermal veins have distinct textures such as carbonate blades and moulds which are generally replaced by silica (forming resistant quartz veins). White saccharoidal (sugary) quartz is also common. The presence of moulds and blades indicates that the entire epithermal system is preserved.

Formation of oreshoots in mesothermal gold-quartz vein
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 ).

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.
