å•ç‹¬ seldom form separate deposits, mostly symbiotic with tungsten, molybdenum , copper , lead , tin and so on. In the process of sorting tungsten or tin in sulfide ore, in order to comprehensively recover rhodium and reduce the niobium content of tin concentrate, low-grade antimony tin ore is produced separately. If pyrometallurgical smelting process such middlings, arsenic complex compositions will produce tin-bismuth alloys, bismuth is not conducive to recovery, while the use of wet processing, can achieve better results.
The chemical composition of the strontium ore used in a plant is shown in Table 1. The medium ore with a particle size between -0.15 and +0.037 mm accounts for 85%. The phase composition of ruthenium is shown in Table 2.

Let's look at the comparison of electric energy, electric energy is not different, because they are all through the same power equipment to operate the equipment, the power of the two is similar, the running time is the same, basically the energy consumption is about the same.
To sum up, for the Closed Cooling Tower energy saving accounting can be strong to open the tower out, and, today are advocating energy conservation and environmental protection, this is the general trend, so the closed cooling tower is more and more favored by the majority of users.
