There are three recovery schemes for the bismuth ore beneficiation process: direct preferential flotation from crude tungsten concentrates; preferential flotation in self-sulfurized ore concentrates; flotation of other sulfide minerals in self-sulfided mineral concentrates The output of tailings usually contains more gangue and wolframite , which need to be removed by shaker selection and magnetic separation. Separation sequence is: → molybdenite bismuthinite, galena ore brass → → → sphalerite pyrite. The volcanic ore bismuth ore is very similar in floatability, and is generally mixed for smelting and then separated. The fine particles are floated and the coarse particles are floated.
We started to manufacture traffic signal pole from 2001 and exported from 2002.
Our firm introduced whole set of good-sized numerical control hydraulic folding equipment(1280/16000) as well as equipped with a series of good-sized professional equipments of armor plate-flatted machine, lengthways cut machine, numerical control cut machine, auto-closed up machine, auto-arc-weld machine, hydraulic redressing straight machine, etc. The firm produces all sorts of conical, pyramidal, cylindrical steel poles with production range of dia 50mm-2250mm, thickness 1mm-25mm, once taking shape 16000mm long, and large-scale steel components. The firm also is equipped with a multicolor-spayed pipelining. At the meantime, for better service to the clients, our firm founded a branch com. The Yixing Jinlei Lighting Installation Com, which offers clients a succession of service from design to manufacture and fixing.
