Quartz will scratch minerals, such as fluorite, that have a lower number on the scale. Suppose you tested a piece of pure gold for hardness. Calcite would scratch the gold, but gypsum would not because gypsum is a 2 and calcite is a 3. That would mean gold is between the hardness of gypsum and calcite, or on the scale.
Calcite: Calcite is also transparent and translucent like halite, but its cleavage is rhombohedreal rather than cubic. Calcite also reacts easily with dilute acid, and lacks halite''s salty taste. Do not test the sample''s taste after testing it with dilute acid however.

The next step was to take the crushed pieces of rock and make them even smaller. We used a heavy metal rod (a broken half shaft from a four wheel drive) and smashed the small bits of rock in a saucepan. The rock needed to be powdered for us to get to all the gold within the rock.
A last warning, if you are removing calcite from a specimen, do not dissolve all calcite. Often it may be the only thing holding the specimen together. A little calcite can provide a nice contrast and make it more aesthetic. In the case of the spinel crystals from the Limecrest Quarry, there are often alternating layers of spinel and calcite.

Calcite and Limestone. February 2017 by Chris Ralph. The other distinguishing feature of calcite has to do with its chemistry. Geologists sometimes take a small bottle of dilute hydrochloric acid out into the field with them because calcite reacts with acids to make a bubbly .
Before mining can commence the land needs to be cleared of timber and vegetation. Alongside this process may be the collection of seeds and/or saplings, for inclusion in a seedbank, which will form the basis of postmining revegetation of the site. Next the top soil is removed and is usually also stored for replacement during rehabilitation.
Calcite has a hardness of 3, SG of, and has a rhombohedral cleavage. Calcite is used in cement making, aggregate, quick lime manufacture, metallurgical uses and for a number of other industrial uses. Limestone is a sedimentary rock, is comprised primarily of the mineral calcite (CaCO3).
Limestone, as used by the minerals industry, is any rock composed mostly of calcium carbonate (CaCO 3). Although limestone is common in many parts of the United States, it is critically absent from some. Limestone is used to produce Portland cement, as aggregate in concrete and asphalt, and in an ...
Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO 3). The Mohs scale of mineral hardness, based on scratch hardness comparison, defines value 3 as "calcite". Other polymorphs of calcium carbonate are the minerals aragonite and vaterite.
