Anshan lean ore magnet is a high silica, low phosphorus sulfur-depleted magnetite, hematite, limonite content, and iron silicate, iron carbonate content higher, which is embedded in fine particle size and uneven, coarse ore A large amount of large particle gangue can achieve monomer dissociation du
First, use The main sorting size range 0-0.25mm magnetic iron ore, to improve product quality and throughput. Second use effect 1. It can ensure that the original output is unchanged, and the grade is increased by two percentage points. 2. It can ensure the yield is 15%-25% if the original grad
After mixing the concentrate powder and the limestone powder, it is rolled or pressed into a green ball having a diameter of 10-30 mm, and dried and baked at a high temperature to consolidate the particles. This spherical mineral is called a pellet. The pellets have uniform particle size, good gas p
In the wet zinc smelting process, go through three leachate purification process, a first material is fired at neutral leaching, the leaching control final pH, the hydrolysis of the impurity element, retained in the leaching residue. The second is a neutral leachate, which must be cleaned and decon
Chinese iron alloy has a serious surplus production capacity. According to the statistics of the Industry Department of the National Development and Reform Commission, as of September 2005, China had a total of 1,570 ferroalloy production enterprises with a production capacity of 22.13 million tons.
The carbonaceous raw materials (coconut, peach kernel, coal, etc.) are activated in the presence of high humidity (800 to 1000 ° C) and a suitable oxidizing agent (steam, air, carbon dioxide) to become activated carbon. Activated carbon is a porous structure with a surface area of ​â€â
As the amount of remaining air increases, the sublimation rate of arsenic decreases, and the desulfurization effect is also improved. When the air consumption is 0.75 lower than the theoretical requirement , the arsenic content in the slag is high. When the baking temperature is 550~ 650 °C A
Environmental awareness has increased over the past 30 years. Cost and maximum recovery are no longer the only considerations for plant design. Efficient, efficient and environmentally acceptable processes, combined with an understanding of maximum recovery rates, do not necessarily lead to the bes
In 2013, under the environment of declining economic growth at home and abroad, China Locomotive Bearing Technology Co., Ltd. has played its own advantages, has been aggressive, hard-working, conquers the trend in technological innovation, production and operation, and continues to maintai
Disc 1. Such zinc powder feeder to the feeder structure and working principle of the conventional disc and the feeder is substantially the same, consists of three parts zinc powder funnel, and the disk drive components. Due to the small amount of zinc powder, the diameter of the disc is generally 1
1. Modern Salt Lake Glauberite Deposit (1) The modern salt lake solid phase mirabilite deposits have high or low grades of salt lake solid deposits, and salt minerals are soluble. Rich ore can be directly exploited in the open air, and the lean ore can be converted by solid-liquid and produced in
As with agitation leaching, in order to accelerate the rate of chemical reactions, oxidants are also required in heap leaching. It is known from the chemical principle of heap leaching that, in the absence of oxygen, the cyanidation reaction of gold cannot be carried out. UO 2 in the ore, if no oxi
