Spring is coming, the weather is good, and the days of opening the skylights are also coming. Many car owners will consider "having skylights" as an important consideration when selecting cars. However, if they only use the skylight as a cool disp
Since vanadium in stone coal mainly occurs in clay minerals, it is easily converted into a soluble state by oxidative roasting. In the late 1980s, most of the stone coal vanadium plants in China used the following process. The traditional process of extracting vanadium from stone coal The main te
When using spiral beneficiation equipment, the configuration must consider the size of the white to facilitate installation, maintenance, and proper use of the site. This configuration is reasonable if the distance between individual spiral beneficiation equipment can be replaced. When designing a
Northeast China is the main production base of boron ore, ore of boron, borax, boric acid and other boron products backbone enterprises are basically concentrated in the region. In recent years, with the market of borax and boric acid products, most of the boron mines in the region have established
Of Salt Lake deposits are mainly distributed in Qinghai, Tibet, Inner Mongolia, mainly solid deposit of salt resources in Salt Lake halite, Glauber's salt, trona, gypsum, carnallite, sylvite, bischofite column Borate , sodium borate, water boron and so on. Liquid deposits containing potassium,
The process of carbonation conversion lead smelting is shown in the figure below. The lead ore is firstly introduced into air or oxygen at 50-60 ° C in ammonium carbonate solution, and stirred vigorously for several hours. Most of the lead sulfide in the ore is converted into lead carbonate and
According to the latest statistics and analysis, in the first half of the year, both the production and sales volume of China's auto market exceeded 10 million, an increase of 12.8% and 12.3% year-on-year respectively, which is higher than the auto industry association’s forecast at the
