Gold concentration may occur as other minerals are leached away over a long period. Ore of sufficient yield is very rare. Gold's Extraction and Purification# Because of gold's inertness some 80% of gold within ore is in its elemental state. There are several processes for extracting, and then purifying it.
ContactNov 20, 2010Gold has a wide distribution within the earth, especially in areas under the oceans and sea. It is found in the form of dust, grains, flakes, or nuggets. The chemical element of gold occurs by amalgamation of mercury and silver. It also forms telluride minerals in its compound form with tellurium. Physical Properties
ContactChemical and physical properties As with most metals, gold is both ductile and malleable. Being ductile means that it can be dawn in to thin wires. Malleability means that it can be pounded in to thin sheets and still maintain its strength. Gold is so malleable that it can be beaten in to sheets so thin they are see-through.
ContactGold crystallizes in the cubic system, although crystals of gold are very rare (it is usually found as irregular plates or grains) Gold has high thermal and electrical conductivities. The only natural isotope of gold is 197 Au; however, 19 isotopes—ranging from 185 Au to 203 Au—have been produced artificially.
ContactA typical arsenical gold ore contains arsenopyrite as the major arsenic mineral. However, some arsenical gold ores, such as those from Nevada in the USA (Getchel deposit), contain realgar and orpiment as the major arsenic-bearing minerals. Pyrite, if present in an arsenical gold ore, may contain some gold as minute inclusions.

ContactThe most obvious physical property of gold is its color. It is one of just a few minerals whose names are used frequently in common language as the name of a color. The color is not altered by tarnish or the development of an oxidized surface. However, the color of gold varies with its composition. The color of gold is not constant.
ContactGold is a chemical element with the symbol Au (from Latin: aurum) and atomic number 79, making it one of the higher atomic number elements that occur naturally. In a pure form, it is a bright, slightly orange yellow, dense, soft, malleable, and ductile metal. Chemically, gold is a transition metal and a group 11 element.

ContactAs we go into the details of chemical properties of gold, you will understand the connection between the general and physical properties discussed above. Gold is considered to be a noble metal. It is chemically inactive. This is because it is highly resistant to react with other elements. The oxidation state of gold ranges from -1 to +5.
ContactNov 30, 20218 Types of Gold Ore- Properties and Ways to Process. Gold mainly appears in the form of natural gold and minerals in the ore such as pyrite, tellurium ore, sphalerite, and gold in gangue, etc. About 70% to 75% of the gold in the deposit is in the form of natural gold, while the other 20% occurs in the form of telluride. The remaining 5% to 10%
