The earth of the portable screen total reserves of tin beneficiation plant about 4.8 billion tons of gold ore, and distribution within the core of about 4.7 billion tons, 86 million tons of mantle, and distributed to the earth's crust is less than 100 million tons. More than 99% of the gold into the core on the earth. The distribution of the gold is in the earth formed in the long-term evolution process. Of the earth's crust development formed in the early stages of the gold abundance is higher, therefore, generally can represent the early archean greenstone belt of remnants of the earth's crust, especially the mafic and super mafic volcanic rock combination, value is higher than the earth's crust au abundance have been all kinds of rocks, might become a gold deposits of the earliest "sources". To sum up, the gold in the earth's crust abundance value is very low, but also has copper, sulphur, kiss kiss with lron, high coltan ore processing melting point, etc, to form the industrial ore deposit, the enrichment of gold to thousands of times, to form the big mining, rich ore and enrichment of gold are thousands, tens of thousands of times, or even higher, its huge gold mine is generally go through a long geological period, through a variety of sources, multiple metallogenesis overlay can be formed.
Gold for crystal at room temperature, the cubic system, vertical lattice in heart, is a rare good natural crystal shape, often irregular granular, crumb, flake, mesh, dendritic, fibrous and spongy. For gold, pure gold containing impurities when its color can be change accordingly. Gold has bright luster, under the white light reflectivity of 74% on average, with the increase of silver content, higher reflectivity, gold increase hardness, density decreased. Bad the volatility of gold, and above the melting point temperature to 1300 ℃ almost no volatile, but in the gas and CO atmosphere more volatile. Gold ore, refers to the use of artificial or mechanical from the mining of gold ore, which also contain other metal impurities and so on. Gold for crystal at room temperature, the Portable gold trommel cubic system, vertical lattice in heart, is a rare good natural crystal shape, often irregular granular, crumb, flake, mesh, dendritic, fibrous and spongy.

Bad the volatility of gold, and above the melting point temperature Carbon in Pulp to 1300 ℃ almost no volatile, but in the gas and CO atmosphere more volatile. |
