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.
5K Flange is a pressure rating for flange norms of JIS B2220 and KS B1503, the JIS B2220 and KS B1503 full pressure rating class are 5K 10K 16K 20K 30K 40K etc, 5K means 5KG pressure, 5K flange is low pressure flange in JIS B2220 and KS B1503 Flange series but also popular using, the flange type SOP SOH and Blind both have 5K pressure.
