The STL water-jacketed Gold Concentrator is a kind of gravity separation equipment. It was developed by Changchun Gold Research Institute Co., Ltd. in 1985 and entered the market. At present, it has been used in many domestic and foreign companies. It is suitable for the recovery of single gold in placer gold, vein gold mines and polymetallic mines, instead of mercury plate operations. The addition of large single gold particles in the collected ore before flotation can further increase the recovery rate of gold mines, and it can also be used from gold-bearing mines. Separate single gold from flotation gold-copper concentrate and flotation gold concentrate.
The main indicators of this series of equipment basically reach the level of similar international products (such as Nielsen gold selectors, etc.). Compared with similar equipment at home and abroad, this series of equipment has the advantages of high cost performance, easy operation, and low maintenance costs.

The US led lighting tbt notification council mainly focused on the tbt notification of the recently released LED lamp test procedure in the United States. The test procedure specifies the method for measuring the lumen output, input power and relative spectral distribution of led lamps. In addition, a method of measuring the luminous flux maintenance rate of the LED light source is also specified to predict the rated life of the LED lamp.
It is understood that these regulations are closely related to LED lighting products, and the United States is one of the major export markets for LED lamps in China. In 2012, China’s exports of LED lamps to the United States reached 10 billion yuan. Once the US notified regulations are officially implemented, it will have a greater impact on China's LED industry.
At present, LED lighting has a small market share, but its longer service life and higher efficiency will increase its demand. The progress of led light source technology will also make them more energy efficient, brighter and more affordable. In addition, lighting manufacturers are also developing devices designed for LEDs to optimize their performance and make them mainstream products in lighting products.
The prospect of high-speed LED development in the United States is also attributed to the demand for energy-efficient lighting products in the Energy Independence and Safety Act of 2007: restrictions on the sale of incandescent lamps. These regulations will work to promote the demand for fluorescent, halogen, high-intensity discharge lighting and led light sources.
According to a research report by the US market research institute Freedonia, the demand for lighting fixtures in the United States is expected to grow at a rate of 7.4 per year, reaching $25 billion by 2016.
