China's first 10 million tons of porphyry copper deposit is expected to be born

Recently, it was learned from Chinalco that with the end of the first phase of this year's drilling project, the two ore bodies in the Jinlong mining area in the Jinlong mining area of ​​Tibet and the Tielong and Teglingnan mining areas are expected to increase by at least 3 million. The amount of copper resources, so that the total amount of copper resources controlled by the two ore bodies exceeded 10 million tons. At the same time, the trend of the integration of these two adjacent mine sections is gradually becoming obvious, and it is expected to become the first 10 million-ton porphyry copper deposit in China.

According to the person in charge of Chinalco Mineral Resources Co., Ltd., China National Aluminum and Tibet Geological Survey Bureau Geological Team has a total of 9 exploration rights in the Jinlong mining area of ​​Duolong Packing Exploration Area. According to the comprehensive research, since 2012, the two sides have carried out the exploration work of the two prospecting rights of Naruo and Tegungongnan. The drilling work has been completed in about 7 months, which is about 30,000 meters, so that the copper resources in the mining area will be co-operated. The initial 1.25 million tons (mainly 334 categories) increased to 7.17 million tons of copper metal, 156 tons of gold, and 1780 tons of silver. Among them, resources of more than 332 categories accounted for more than 70%, showing the prospect of world-class deposits.

This year, Chinalco and the Geological Five Team plan to invest 70 million yuan to increase exploration efforts. At present, the drilling work has been completed more than 17,000 meters. The borehole of the final hole has controlled the ore body with a maximum thickness of 1,121 meters and drilled. The ore body is still below the hole and does not penetrate the ore body. It is estimated that the current controlled ore body is expected to add at least 3 million tons of copper resources in 332 categories this year, so that the ore body copper resources controlled by the two ore bodies exceed 10 million tons. The thick and rich ore bodies in the Rongnao section extend stably to the east and south. The deep and thick ore bodies in the Naruo section extend stably to the west and south, and the trend of connecting two adjacent ore sections is increasingly obvious.

At present, the Tibet Geological Survey Bureau and the Sichuan Hongda Company have acquired 6.43 million tons of copper ore resources in the two deposits of Douba and Bolong, plus the copper resources controlled by the Daro, Rongnao and Dulong ore districts. The amount has reached 16 million tons, and the prospecting potential has exceeded 20 million tons. The Duolong Packing Exploration Area has become China's first world-class porphyry copper ore concentration area.

It is reported that the Jinlong mining area in the Dulong self-contained exploration area is a national-level self-contained exploration area jointly explored by the Ministry of Land and Resources, the People's Government of Tibet Autonomous Region and Chinalco. Jinlong Company was founded by China Aluminum Tibet Mining Co., Ltd. and Tibet Geological Survey Bureau Geological Group 5 on November 29, 2012 in Golmud, Qinghai. Currently, there are 9 copper and gold exploration rights in Tibet. In addition to Naruo and Tegungong South, there are also Bunkang Namugang, Sena, Senadong, Qierqin, Duodudong, Anglong and Duowo East. The total exploration area is 59.261 square kilometers.

Hard Acrylic Courts are suitable for professional competitions and training. The company uses 100% imported acrylic water-based materials, in full compliance with environmental requirements, has good wear resistance, waterproof, sunscreen, non-slip, can be laid indoors and outdoors asphalt or cement surface.
Hard Acrylic Product Features:
1,100% silicone resin composition, non-toxic, non-asbestos, in line with environmental requirements;
2, all-weather acrylic sports venues UV material, has excellent wear resistance, long weatherability, safe and comfortable;
3, the color is stable, does not fade, no blistering, no cracking, no mold, long life, durable 5 years, cheap, easy maintenance;
4, non-slip performance is good, the athlete is not easy to slip.
Basic requirements:
â‘  flatness with 3m ruler in either direction the height difference between two points does not exceed 3mm;
â‘¡ cement-based maintenance of at least 28 days, at least curing asphalt foundation for 14 days;
â‘¢ cement-based pulp with wood pulp to mention when mentioning pulp, do not sprinkle cement powder or shovel to receive mirror light;
④ The entire stadium drainage slope of 3-5 ‰, drainage direction parallel to the direction of drainage in the side of the network;
⑤ cement foundation can be set up in the middle of a network of expansion joints, division line can not be set expansion joints;
â‘¥ cement-based cracking is difficult to avoid, the hair does not affect the fine slits play, but structural cracking should be avoided, expansion joints and cracks can be used two-component polyurethane material into the crack.
Waterproof bottom:
With acrylic primer 1: 3 ratio of watered, fully stirred, roll coating on the base surface, after rolling carefully check the no missing place.
Bottom fill:
Acrylic primer with 1: 2: 2 ratio plus 60-80 mesh quartz sand and 425 cement, watered with water and then add cellulose for full mixing. Fill the depression inside the venue to reduce the phenomenon of water, so that the stadium ground leveling requirements.
Strengthen the middle:
Acrylic fabric at a 1: 0.5: 0.1 ratio of 60-80 mesh mixed quartz sand and 250 mesh quartz powder, watered thoroughly mixed with imported rubber scraping rake scraping, on the basis of providing a homogeneous, thick cushion, Increase the stadium strength, improve the quality of the entire stadium surface.
Texture surface:
Acrylic fabric at a ratio of 1: 0.25: 0.25 80-100 mesh mixed quartz sand and 250 quartz powder, fully watered mixed with imported rubber scraping rake scraping the audience a layer of scratch, so that the surface has a uniform texture Effect, increase wear-resistant function and adjust the ball speed. After this layer of dry solid, with a shovel shovel out of the sand, sweeping away the dust.
Course marking:
Acrylic drawing material directly watered, draw the standard course boundaries of two.
