The Island copper mine, located on Vancouver Island, British Columbia (Canada), functioned from 1970 to deposit was Canada''s third largest copper mine and produced copper, gold, silver, molybdenum and a byproduct called Rhenium. When the mine closed, more than one billion tons of material had been moved, leaving the deepest excavated depression below sealevel on Earth.

Calcite is one of the most common minerals on the Earth''s surface. It is a often part of sedimentary rocks, especially is also the primary mineral in metamorphic marble.. It is a chemical or biochemical calcium carbonate with the formula CaCO is a carbonate mineral. It can be a vein mineral in deposits from hot springs, and in caverns as stalactites and stalagmites.

I have not commented on the calcitearagonite tests as that subject has been well and excellently covered – between the composing and the posting of this one – in a recent thread of postings in the Analytical Techniques section of Message Board on ).

Calcite is common and abundant throughout the world. The material has little intrinsic value since it is not scarce. However, calcite is one of the most difficult of all minerals to be cut because of perfect cleavage in 3 directions. The cost of faceted stone is therefore mostly in the labor of cutting.

Precipitated Calcium Carbonate. PCC stands for Precipitated Calcium Carbonate—also known as purified, refined or synthetic calcium carbonate. It has the same chemical formula as other types of calcium carbonate, such as limestone, marble and chalk: CaCO3. The calcium, carbon and oxygen atoms can arrange themselves in three different ways, to form three different calcium carbonate minerals.

What is Mohs Hardness Scale? One of the most important tests for identifying mineral specimens is the Mohs Hardness Test. This test compares the resistance of a mineral to being scratched by ten reference minerals known as the Mohs Hardness Scale (see table at left). The test is useful because most specimens of a given mineral are very close to the same hardness.

Limestone, sedimentary rock composed mainly of calcium carbonate, usually in the form of calcite or aragonite. It may contain considerable amounts of magnesium carbonate (dolomite) as well; minor constituents also commonly present include clay, iron carbonate, feldspar, pyrite, and quartz.

Limestone. Limestone is a sedimentary rock composed mostly of the mineral calcite and comprising about 15% of the Earth''s sedimentary crust. It is a basic building block of the construction industry (dimension stone) and a chief material from which aggregate, cement, lime and building stone are made. 71% of all crushed stone produced in the is either limestone or dolomite.
