Sep 02, 2011 This can be an indicator of gold. Iron Staining & Gossans: Not all veins produce much quartz – gold bearing veins can consist of calcite or mostly sulfides – which often weather into iron stained spots when the pyrites convert to iron oxides. Large amounts of iron oxides like hematite, magnetite and ironstone can be favorable indicators.

May 18, 2021 Hydrothermal veins supply much of the Earth’s gold. Their propensity to contain “bonanza” occurrences of gold that have concentrations millions of times greater than the concentration of gold in Earth’s crust makes them important targets for exploration and resource development. The mechanisms by which such hyperenrichment occurs are enigmatic.

Jul 12, 2013 Epithermal gold deposites are among the richest gold deposits in the world, with some bonanza-grade ore shoots containing more than 1000 g/t gold-equivalent to a kilogram of gold for everyone tonne of rock mined. The tonnage of ore in epithermal veins is typically smaller than other types of low-grade gold deposits.

Sep 29, 2016 The uses of calcite, in the form of limestone, for building stone and marble, for making lime and cement, for fluxing iron ore, etc. are well known. For these purposes, limestone is a cheap material, a dollar or two a ton. Pure calcite is ground to a fine powder, and is used instead of whiting. White calcite of good cleavage is used as stucco dash.

Calcite CaCo 3 As a very common mineral, calcite can be seen in many different rocks including limestone, dolomite, and marble. Although calcite is commonly white, it can appear in various colors due to chemical impurities. Calcite can be distinguished from other similar looking minerals (such as quartz and feldspar) by its effervescent ...

Fluorite is one. Suppose you had a piece of pure gold. You find that calcite scratches the gold. Gypsum does not. Gypsum has a hardness of 2 and calcite is a 3. That means the hardness of gold is between gypsum and calcite. So the hardness of gold is about 2.5 on the scale. A hardness of 2.5 means that gold is a relatively soft mineral.

Calcite’s crystal system is hexagonal and its crystal forms are more varied than its colors. The most common crystal forms are rhombohedral and scalenohedral, but may also be tabular, lenticular, stalactitic, fibrous, massive and twinned to name a few. Another distinctive feature is its perfect rhombohedral cleavage.
