Current Status of Exploration and Development of Gold Resources in China

Although China is one of the first to recognize and developing countries to use gold in the world, but specialized gold mine geological work started late. From 1949 to 1975, it was basically the initial stage of development and exploration of gold deposits in China. Since the 1980s, China's exploration and development of gold deposits has entered a relatively fast development stage, and a number of medium and large deposits have been explored in Jiaodong, Xiaoqinling, Yanliao, Daqingshan, eastern Liaoji and Shaanxi-Gansuchuan triangles. At the same time of the continuous development of gold resources and production bases, a batch of gold was formed in the northern gold-producing areas of Xinjiang, which are centered on Altai and Tianshan, Guangdong, Yunnan, Guizhou, Guangxi, Hainan, Gansu and the middle and lower reaches of the Yangtze River. Mineral resources and production base.

In recent years, a number of large and extra-large gold deposits have been discovered in the western region by strengthening the investigation and evaluation of key metallogenic belts. In addition, based on the small depth of exploration in China, breakthroughs have been made in deep exploration in key mining areas, such as the existence of the second rich belt in the deep Qinling Mountains, in Jiaodong, Chifeng Jinchanggouliang, Jilin Jiapigou, Hunan Xiangxi Gold. A number of old mines, such as mines, also found production and connection resources at a depth of 1000m, which played a demonstration role in deep exploration. The gold industry has added about 500 tons of gold resources every year. In 2006, it exceeded 650 tons. Among them, China National Gold Group Corporation has obtained more than 1,000 tons of gold resources since 2007. The above-mentioned exploration progress has enabled China's gold industry to achieve new exploration reserves more than production and consumption reserves for several years. At the same time, gold production has also shown a trend of continuous growth, and gold production has been among the highest in the world.

For a long time, Chinese production of primary resources of gold beneficiation of easy to stone as the main target. However, about 30% of the proven reserves are refractory ore, mainly fine-disseminated gold mines. The accumulated proven reserves have exceeded 1000 tons and become the most important Carlin-type gold ore deposit in the world except the United States. About 700 tons of high- arsenic and high-sulfur ore in the proven reserves of such deposits are difficult to cyanide directly. In addition, at least 40 or more refractory gold deposits with a capacity of 1 to 100 tons cannot be exploited due to environmental problems. The treatment of these difficult-to-use “staying mines” has become one of the main “bottleneck” issues affecting the sustainable development of China's gold industry.

Piston

Engine piston is a vital component of an internal combustion engine. It is a cylindrical metal part that moves up and down inside the engine cylinder. The piston is connected to the crankshaft via a connecting rod, which converts the reciprocating motion of the piston into the rotational motion of the crankshaft.
