Now for paigeite Division, mainly, have

Resources of pine forest of the worlds there is a lot of, but it is not a lot of countries with pine forest resources, according to show of statistics of 2008 that world pine forest reserves, about 170 million tons, about 410 million tons of a spare basis, Turkey, Russia, the United States and China. countrys reserves the account approximately for 97 % of stocks of total of the worlds. The Chinese stocks and a spare basis - respectively 25 million tons and 47 million tons, making 14.7 % and 11.5 %, in the fourth place in the world. Now for paigeite Division, mainly, have the following aspects: usual process of division, damp process of division, pyrometallurgical division process. Usual process of division - the ore nature, using usual process of enrichment for re-election, magnetic division, swimming and other minerals to sort in a pine forest material.

Damp process of division, mainly, deals with iron ore containing pine forest, concentrate magnetic process of division, using production of a vyshchelachivaniye of acid of pine forest, the rest of a vyshchelachivaniye of iron ore concentrate magnetic to make a zheleznobor separate. Features of damp process of division should be completely used in each of elements in ore, pine forest complete division of iron, high acid consumption, high costs of production, the process sewage, difficult to be located, problems of environmental protection are difficult for solving. Unlike damp process of division, pyrometallurgical division process first ironmaking then pine forest, process is divided into a method of a blast furnace, and thorough reduction of a phase - плавят division. The scientists based on chemistry of ludwigite, mineral features of structure, think out a furnace method to a full development of ludwigite process, at first by means of enrichment to receive iron ore containing pine forest concentrate, in a blast furnace on 13 m to make the iron test of division of the pine forest, 8000 tons processed in total ore to make to the drill, the boric acid, containing pine forest cast iron in chushka and water sulfate of magnesium products. Thorough reduction of a phase - a thawing method of division - ludwigite ore or after the end processing ludwigite, use not, koksovy coal in a firm condition approximately in 1100 reduces 80 % to 90 % of an oxide of iron to metal iron. Ore after it is restored through magnetic to receive magnetic products which containing iron metal and slag of an oxide of pine forest, and then electric melting division of the furnace, receive iron containing pine forest or a half of pine forest of steel and high activity of slag rich with pine forest, restoration of iron and oxidizing pine forest, was more than 95 %; according to reviews of metal iron of the supplier of the powders used in areas of the car containing pine forest, metallurgy, chemicals, construction materials, agricultural and so on, can replace the high prices of an alloy of iron of pine forest, chrome, molybdenum, nickel metal. It is more than 20 % of the maintenance of an oxide of pine forest in slag rich with pine forest can be used to make boric acid and to the drill.
