---About rock ore

   Also called the gold mine, also known as gold bullion, produced in mines. Most of the gold deposits, which are made up of underground hot springs, are precipitated by fine cracks in the rock, often in the cracks in the rocks. Most of mine gold associated with other metals, which in addition to the gold and silver, platinum, zinc and other metals, other metals not made known prior to gold bullion. Mine gold produced in different mines and other metal components contained in different, therefore, different degrees of fineness, generally between 50%-90%.

   According to the structural state and gold content of gold, the gold deposits can be divided into three categories: gold ore, gold mineral and gold bearing mineral. The so-called gold independent mineral, refers to the gold mineral and gold minerals in the form of gold, which is the most important form of gold in nature, but also the main object of industrial development and utilization. Up to now, 98 kinds of gold minerals and gold bearing minerals have been found in the world, but there are only about 47 kinds of minerals, and the direct utilization of minerals is only more than 10 kinds.

---Features

(1)  The distribution of most placer gold deposits is closely related to the origin of rock gold deposits, but a few are limited to other geological conditions.
(2)  The old basement strata and a large area of placer gold metallogenic zone mostly distributed in the gold abundance of higher intrusive rocks eroded areas.
(3)   Most gold deposit with multi-source, such as material source of gold placer gold basin is mainly the lower Cretaceous Banket, followed by two Erdaowa group in dispersed auriferous quartz veins, auriferous conglomerate in multi supply. As in the acidic magmatite area on both sides of the river in the gold bearing quartz veins and altered fracture zone around the associated gold and three century gold bearing conglomerate is the source of placer gold supply.
(4) Placer deposit formed against the river and concentration, coming to be gold deposit. for example, basically  all the rivers are the average content of 0.01 grams per cubic metre. The content at the bottom of the river is more than 30 grams per cubic meter.
---Processing product

   Rock gold ore is mainly exist in stone, therefore to get the gold from stone, has to been crushing - grinding - concentration several processes, mainly need the equipments: Jaw crusher, Ball mill, Spiral classifier, Wet pan mill, Shaking table, Flotation equipment etc.
