Application Of The "Three Components" Mineral Prediction Principle In Assessment Of Nontraditional Mineral Resources

Platinum Grope elements (PGE), is scarce, valuable, and uneven in the distribution (such as South Africa alone accounting for the global proven reserves 81%, Russia 17%, the United States and Canada about 2%), and in the aerospace, automobile, electronics, pharmaceuticals, jewelry, and other areas of increasing demands, which result in platinum mining with severe resource constraints and extraordinarily intense international market conflict between supply and demand delete, therefore, North America had to recycle platinum metals from tail gas purification of waste cars. In recent years, our country platinum resources consumption rates per year is the second in the world. (After exceeding that of Japan and being the top of the world in 2000), jewelry consumption in China which is beyond over Japan and the highest in the world 2000, has maintained the rapid growth (for example, in 2002, Chinese jewelry consumption reached 1.5 million oz, while the whole Europe was only 170,000 oz) for many years; Besides, the domestic auto industry's rapid development will spur automobile tail gas purification catalyst platinum consumption. So, as far as in China, platinum resources situation is even more grim. Though Jinchuan, and Jinbaoshan Cu-Ni-PGE deposits, platinum is a accompany element with copper nickel, and the grade is rather low. Domestic demand for platinum grope metals is still dependent on imports, which impact on national security (international market price of a platinum increased once and again, 692 U.S. dollars per ounce in 2003, the highest price for 23 years of history ,and in 2003 -2004 years it once occurred that in the international market Chinese could not purchase platinum; Since 2002 ,our country has increased the retail price of platinum jewelry nearly 20 times, just at the beginning of 2006, the retail price of platinum increases two times ,and the 990Pt reached 348 yuan per gram in Wuhan; Some jewelers had to use "palladium jewel" to replace the "platinum jewel"). Naturally, in recent years, platinum group metals mineral prospecting has become a new hot spot. For example, 2002 platinum group metals investment was 104 million U.S. dollars, accounting for 6.0% of the world's non-fuel mineral prospecting solid investment, increasing 52.9% compared with that in 2001; in 2003, it continued to invest in platinum family metals prospecting warm, reaching 131 million U. S. dollars, increasing 26% compared with that in 2002. A group of industrial significance platinum group metals deposits are found, for the survey for the project and outlay increased. Such as in South Africa Sheba's Ridge areas, PGE metal reserves is 557 tons, and Blue Ridge areas, Au and PGE metal reserves is 147 tons; In Panton areas, Australia, PGE metal reserves is 140 tons, and in Munni areas, PGE metal...
