Lead-zinc ores divided by the degree of oxidation of different ores (lead or zinc oxide <10%), oxidized ores (lead or zinc oxide of> 30%) sulfide ore, ore mixing (lead or zinc oxide of 10% to 30%) . Press different ore useful components, can be divided into lead ore, zinc ores, zinc ore, copper, lead and zinc ores, sulfur, lead and zinc ores, copper, lead and zinc ores sulfur, tin-lead ore, lead ore, antimony, zinc, copper ore and the like . According to different ore structure, it can be divided into disseminated ore, dense block ore, breccia ore, strip ore, fine vein disseminated ore.

The beneficiation test of lead-zinc ore, sulfide ore is usually carried out by flotation. The oxidized ore is flotation by flotation or re-election with flotation, or after flotation by sulphide roasting, or after re-election, treatment with sulphuric acid and then flotation. For multi-lead-zinc ore containing metals, typically magnetic - floating, heavy - floating, heavy - Magnetic - floating jointly processing methods.

Steel Aluminum Extruded Finned Tube

The extruded finned tube is a kind of heat exchange element that has been widely used in recent years. The previous fin forms were all wound fins, string fins, and welded fins. Because the heat transfer coefficient of steel is relatively low, the heat transfer efficiency of the finned tube made of steel tube sheet is not high.

embedded finned tubing offers exceptional thermal efficiency at higher temperature ranges with solid fin-to-tube contact. Fins are mechanically locked into a helical groove in the outside of the tube. Rollers press displaced metal from the groove against the base of the fin to form a lasting metal-to-metal bond.

Although the aluminum material has high thermal conductivity, the mass density of the aluminum material is relatively low, and it cannot withstand high temperature and high pressure. The melting points of the two materials are different, so they cannot be welded.
