 The brief introduction of copper ore

1.The natural attribute of copper ore

The copper ore is one of the ancient metal that human beings have discovered. About ***0 years ago, Human beings began to use copper. We can divide the copper into 3 kinds: native copper, oxygen copper ore, and copper sulphide.

There are little storage of native copper and oxygen copper ore in the world. Nowadays *0% of copper is refined from copper sulphide.

The copper content of this kind of ore is extremely low. It is about 2%to3%. The symbol of element is CU. atomic weight is *3.*4.specifice gravity is 8.*2,and the melting point is ***3Co.
2. The types and distributing of copper ore

The types of copper ore are various and they are divided into the following types according to the industrial types:
(1) porphyry  (2)rammell   (3)copper nickel slfuret   (4)pyrite
(5) copper-uranium-gold   (6)native copper   (7)veins  (8)carbonatite (9) scarn

Porphyry Type
porphyry type have large storage and low grade .however we can mine the copper deposit ore with mechanization.
Distribution

Porphyry copper ore mostly distribute incircumpacific belt, includingporphyry copper belt along withcontinental margin of North America and tethys.Porphyry copper belt include Hungry, Yugoslavia, Iran and so on. The belt also distribute in Middle Asia***-Mongolia

2、Rammell type
   Rammell type of copper ore accounts for *0% of world reserves .The characteristic of rammell type is that large scale of mineral deposit and high state.

Distribution     
This kind of copper deposite has a large distributing in the world except the above-mentioned copper belt. It also covers original Soviet Union, America. In recent years , we can also find this kind of copper in Afghanistan and Brazil.
3、 Pyritetype

The pyrite type of copper ore refer to the mineral deposit with large amount of pyrite and certain amount of copper, lead, and zinc which affected by the volcano of seabed. This kind of mineral deposit is also called massive sulphide mineral deposit in the west.
Now there are al least **0 types of this kind of mineral deposit. Canada, America, original Soviet Union, Spain, Portugal, Cyprus, South Africa, and Japan are important producing area of this kind of mineral deposit.
4、Massive sulphide ore
 This kind of modern mineral deposit was discovered at the first time around north latitude *1degree in east of pacific ocean in ***8. Although the state of copper and zinc is very good, we find a metal massive sulphide mineral deposit with *5 million, which is **0 meter long, **0 meters width, *5 meters high. This is the first time to meet the requirement of industrial requirement. The most content of copper in the ore is *1%, the zinc, silver molybdenum and zinc are 0.8%,0.*3%,0.*3% respectively .it is also with a little of silver.

This kind of mineral deposit distribute in Canada, America, original Soviet Union, Australia, Finland and China
Other types
Except the above mentioned type, it also include the type of naives, native copper , carbonatite, scarp and so on. They account for 3.6% of  world total reserves.

Some global and regional copper ore belt
    (1) Cenozoic copper and gold belt along pacific, especially in Chile in the east of pacific, southwest of Canada and southwest of pacific
    (2) Porphyry copper belt in the Alps and Himalayas, including original Yugoslavia, Iran, Pakistan and china.
    (3) Paleozoic Porphyry copper belt in Middle Asia-；
    (4) Middle Africa **-Zambia and Zaire sand shale copper ore belt
    (5) America –Canada five lakes area
    (6) Canada pyrite copper ore concentrated area
    (7) Middle Europe Poland **-German

2、The brief introduction of chrome ore

1、Characteristic of the Raw Material of Chrome Ore

There are about *0 types of chrome ore which can divide into the type of oxygenation, chromic acid and silicate and also include a little hydroxide, iodated, and sulphides.
Chrome ore with industrial value belong to chromspinellide. Their chemical formula is （Ｍｇ、Ｆｅ２＋）（Ｃｒ、Ａｌ、Ｆｅ３＋）２Ｏ４or（Ｍｇ、Ｆｅ２＋）Ｏ（Ｃｒ、Ａｌ、Ｆｅ３＋）２Ｏ３，the content ofＣｒ２Ｏ３is  from１８％to６２s%.

2、The types of Chromic Ore
1、chromite
The element of chemic is（Ｍｇ、Ｆｅ）Ｃｒ２Ｏ４people usually call Ferro Chromite ore and magnesiochromite as chromite ore.

2、Cromopicotite
The chemical element is（Ｍｇ、Ｆｅ）（Ｃｒ、Ａｌ）２Ｏ４，the content ofＣｒ２Ｏ３is about３２％to５０％。The physical aspect and usage and shape are the same as the chromite ore.

3、The usage and technical
