China's iron ore resources are widely distributed, the full range. The main characteristics of Chinese iron ore resources: iron ore origin are widely distributed, but the reserves were relatively concentrated; ore processingcomplete deposit type; lean ore bonanza less complex ore types; with (total) of raw components.
(1) iron ore origin are widely distributed,magnetic separator suppliers but the reserves were relatively concentrated
Has to identify the origin of the iron ore found throughout the country's 29 provinces, municipalities and autonomous regions, more than 660 counties (banners), but in groups, as with output, showing the relative concentration of the characteristics of the distribution. As mentioned earlier the nine districts accounted for 68 percent of the country is to maintain iron ore reserves.
Mining area reserves, large scale mining area (the reserves of more than 100 million tons) 101, the total reserves, accounting for 68.1 percent of the country's reserves; medium-sized mining areas (reserves of 0.1 to 100 million tons) 470 Department, the total reserves accounted for 27.3 percent of the country's reserves; small mines (reserves less than 10 million tons) 1 263 at only 4.6% of total reserves.
(2) types of deposits
Geological prospecting and mineral deposits research results show that China's iron ore deposit types have been found in the world iron ore genetic types have been found in China, Precambrian BIFs weathering crust of iron ore are proven reserves, which the sedimentary-metamorphic, reserves accounted for 57.8%, ranking the first of the various types of iron ore deposits, followed by contact metasomatic - hydrothermal (12.7%), the magma type (11.6%), sedimentary (8.7% ), and volcanic - intrusive activities related to the type (4.7%), weathering, leaching type (1.1%), other types accounted for 3.4%. Difference is that the contact metasomatic in China - a higher proportion of hydrothermal and magmatic reserves and the world.
(3) low grade ore, high-grade ore complex ore types
Depleted ore reserves of iron ore reserves to maintain 45.2 billion tons, accounting for 97.5 percent of the country's reserves; iron an average grade of about 55% directly into the furnace of rich iron ore reserves of 1.174 billion tons, accounting for reserves of the country 2.5%, and the formation of a certain scale of mining, and even less able to separate the rich iron ore mining.
China's iron ore complex natural type, type of ore (two kinds or more than two kinds of magnetite ore, vanadium and titanium magnetite ore, hematite, Ling iron ore, brown iron ore mirror, iron ore and mixed ore mixed with ). Magnetite ore in the iron ore reserves to maintain a maximum of (55.5%), is currently mined ore types; vanadium-titanium magnetite ore (14.4%), are complicated, but the dressing and smelting technology has been basically solved, is currently exploitation of the main ore types; hematite (18%), Ling iron ore (3.4%), brown iron ore (2.3%), mirror, iron ore (1.1%), mixed ore (accounting for 5.3%) and other types of ore, sorting performance is poor, its low grade ore mostly untapped.
(4) with (of) the raw components
(Paragenetic) components of iron ore reserves in China now with about 1/3 of the reserves of the country, involving a number of large and medium-sized iron ore district, such as Panzhihua, red cells, white horse, Tai Wo, temple, and Daye big top, Huang Gang, Tsui Hong Shan, Jinling, Dabaoshan Huashugou, Ma On Shan, Lujiang, Longyan and Hainan Shilu such as iron ore area. With (total) students useful components: vanadium, titanium, copper, lead, zinc, tin, tungsten, molybdenum, cobalt, nickel, antimony, gold, silver, cadmium, gallium, uranium, thorium, boron, germanium, sulfur, chromium, rare earth, niobium fluoride, gypsum, limestone and coal, more than 30 kinds. This is the main features of China's iron ore resources, and thus the comprehensive utilization of the ore is an issue that must be addressed.
