Scrap iron steel production is an important resource burden, especially in electric furnace steelmaking, to be equipped with 80% of the scrap. Replacing pig iron steelmaking with scrap steel can also shorten the smelting time due to its low content of harmful elements such as sulfur and phosphorus
Read moreIndium is one scattered metal content in the crust is very low, no separate indium deposits, primarily enriched in sulphide ores, in particular the sphalerite, zinc smelting, lead byproducts. The separation and extraction methods of indium include leaching resin separation, liquid membrane separat
Read moreI. Overview The water resources in most areas of China, especially in the north, are relatively scarce. With the development of the economy and the improvement of people's living standards, the demand for industrial, agricultural and domestic water has increased year by year, and the developme
Read moreAt present, iron ore resources in China in iron ore resources easily selected dwindling iron ore resources is characterized by lean ore more high-grade ore less, associated minerals much more complex component ore, ore mostly fine dissemination size, to cause some dressing Difficulties. Technically
Read moreThe barite has a large specific gravity, and the proportion of its commensal gangue is generally small. The re-election method can be used to treat the barite ore to obtain a better beneficiation effect. So what equipment is needed to re-select the barite mine? The barite re-election equipment ref
Read moreThe unloading valve is the simplest type of ore-mining equipment. Its operation is controlled by the human lever or by the operator through compressed air, hydraulic piston, motor drive and other methods. They can only be successfully used for the ore-mining of free-flowing materials and for the un
Read moreThe purpose of the test is to provide a basis for the evaluation of the ore's ore selection and the possibility of development and utilization. The deposit is Qinling - continental orogenic belt of the western extension of the Kunlun orogenic belt part Qilian, is typical of magma genesis of ba
Read moreTungsten was discovered in 1781 by the Swedish chemist CW Scheele. To the beginning of the last century, due to a number of application development tungsten, such as in 1900 for the first time demonstrate the use of high-speed steel and tungsten bulbs with tungsten as an alloying element in the Par

Read moreBoron ore mining and factors develop depends on the type of deposit, orebody form, occurrence, size, physical and mechanical properties of the rock minerals and burial conditions. Since China's solid boron deposits are generally small in scale, most of them are exposed to the surface, but the e
Read moreCore reading: Cobalt is associated with iron , copper and nickel ore. There are mainly four kinds of cobalt ore in China: copper nickel cobalt ore, copper cobalt ore, iron cobalt ore and cobalt ore. Different beneficiation methods are required for different main minerals. Metal processing technical
Read moreHenan is an important molybdenum mine base in China, and it is associated with abundant low-grade scheelite in molybdenum deposits. Since a long time has been focused on the recovery of molybdenum in the beneficiation , a large amount of white tungsten is discarded as tailings. In order to rational
