China's copper deposit type

Copper Deposit Types of Table 1 below:
Table 1 Types of copper deposits in China
Deposit name
Surrounding rock type
The main metal minerals and gangue minerals
Example
Porphyry copper deposit
Acidic or porphyry or phyllite (of sericite, chlorite silicide)
The metal minerals are mainly chalcopyrite and molybdenite , followed by porphyrite, azurite, malachite and beryllium. Non-metallic minerals are mainly quartz and sericite. The main component is associated beneficial pyrite, molybdenite, gold, silver, etc.
Jiangxi Dexing Copper Mine
Shanxi Zhongtiaoshan Copper Mine
Layered copper ore
Dolomite or dolomitic limestone (silicification, dolomitization, chlorite)
The metal mineral oxidation zone is mainly composed of malachite and azurite. The secondary enrichment zone is mainly composed of chalcopyrite and porphyrite. The primary zone is mainly chalcopyrite and pyrite. The gangue is mainly composed of quartz and carbonate.
Yunnan Yimen Copper Mine
Skarn copper mine
Mostly acidic or acidic igneous rocks and carbonate rocks
The main metal minerals are mainly chalcopyrite and pyrite, with a small amount of porphyrite and magnetite. The gangue minerals are garnet , diopside , sericite, chlorite
Anhui Tongshan Copper Mine, Fenghuangshan Copper Mine, Shizishan Copper Mine, Hubei Fengshan Copper Mine
Copper-bearing pyrite
Fine-bijiao porphyry (green mud, petrochemical, silicified)
The metal mineral oxidation zone is mainly composed of malachite and azurite. The secondary enrichment zone is mainly composed of chalcopyrite, and the primary zone is mainly pyrite and chalcopyrite. The gangue minerals are mainly quartz, sericite, calcite and gypsum . Associated beneficial ingredients are pyrite, lead , zinc , gold, silver, etc.
Gansu Baiyinchang Copper Mine
Jiangxi Wushan Copper Mine

Natural Barium Sulfate

Application:


It is more cheaper than Precipitated Barium Sulfate, the use of natrual barium sulfate is the most enconomic formulation for making 40-60°gloss powder and wrinkle powder.


It is especially suitable for matte and wrinkle powder.


So it can lower cost instead of precipitated barium sulfate in powder coating.
