Italy, Sicily, rock salt and potash

Cage capable of carrying 54 miners. No. 3 shaft is a ventilation shaft, deep 3t0m. In recent years, continued to move forward with the mining work, with working farther and farther away from the shaft. To this end, and from the ground trampled cut out a face inclined towards the shaft of gold is about. 1,920 m, slope is 16.5%. Installed a shaft in the transmission energy. Force of 500t / h of the tape transport, although the size may be inclined to allow vehicles to pass; the ramp and through the layer of bischofite (MgC1.61-1O), combined with the mineral deliquescence, resulting need to keep shaft maintenance. Solution is to install a cooling device shaft, which not only reduces the bischofite layer temperature and humidity inside the lower shaft. Inclined to reduce the upper sections of the dust, but also inclined asphalt paving. In addition, Pascluasia ~ new cut out of a 290m deep shaft mining area may improve the current ventilation conditions, in particular the need to meet the diesel-powered equipment. First, mine is willing to stay for the needle to open gold and silver telluride minerals and carnallite developed, but the two did not put the current mineral mining. Mine is currently the only mineral that is mined potassium magnesium sulfate. Mine consists of five potassium magnesium sulfate seam, each seam thickness and continuity of up to cut out all that can be adopted standard, there is a rule these seam Du Fu in the syncline. The first mine was the top-screen bonanza l Ju; layer; while the second ledge of the workers: the highest value business development, and its thickness. For the 30 \above. As a result of seam K. O content is high, especially in the first seam, thus the safety of gold and mineral mining area of transport has brought many problems to solve as follows:. Co-extensive use of resin, revolves around the rock roof bolt support. Chuo past years, over 20,000 have been installed roof bolt. '. Jim purchased a proven 4 ~ Pingon pry rock machine. . Reduce the explosion, to make use of continuous mining machine (mine are 7 sets of continuous mining machines in use, please see table below). ? The endangering the safety of the local operation using the remote installation of a shipment of a work of unloading machine. 'Current daily output of ore Psq servant asia stable at about 60o0 ~ 65oot. Eleven: Table 1. PaSqtIasia ore processing plant with a major mining equipment. 'Capsule purpose Sicily before the magnesium potassium alum, two stag processing plants, including one at the Pasqua-sla;'. India Pasqtmsia ~ downstream location, its annual processing capacity of about 1.5 million t; another 1, O Pa Tiaojishan Formation j reed against left foot more than a dozen Yu recommended a slightly lower annual production capacity of processing plants located in the vicinity of Agrigento province Castelte plus i, the plant is responsible for processing ore from the Realmonte magnesium and potassium alum Racalmuto ore mine. In Pasquasia; ~ 212 plants, the first of the potassium magnesium sulfate mineral flotation, flotation concentrates are transferred after the SOP. To meet the needs of industrial water processing plant built in the vicinity of a dam which blocks the water capacity of the dam is about 10 million m. Output of the processing of waste brine being let go, re-use issues for the brine has conducted a number of studies, including the permanent use of the brine production by-products, such as magnesium oxide, sulfuric acid, ultra-fine sodium chloride, artificial carnallite and magnesium chloride and its secondary products. However, for the production of the huge investment compared with the market situation does not pay. Nevertheless, there are some small factories being built l in their final products (such as ultra-pure salt side) of the sales estimates will not be a problem. Han Yan translated from the British \Industry = 『change the destiny, although higher than in 1991, the world consumption of phosphate rock production, but the market remained stagnant. In 1991 the world production of phosphate 1.503d 'Lt, compared with 1990, reducing the 7,000,000 t. 1991 World phosphate consumption in a large decrease, reducing the 9,000,000 t. 1991 World phosphate supply and demand decline reflects the former Soviet Union and Central European political and economic instability. the former Soviet Union is the world's second largest P mine-producing countries in 1991 than in 1990 reduced the annual production of 300 million t, reached 33.3 million t, mainly due to a number of republics from 1988 real
