Lead is one of the earlier metal extracted from human beings out of lead-zinc ore. It is the softest of the heavy metal, but also more than one of the major metals, with blue-gray, the hardness of 1.5, the proportion of 11.34, melting point 327.4 ℃ electric slag machine parts, boiling point 1750 ℃, good malleable, easily with other metals (such as zinc, tin, antimony, arsenic, etc.) made of alloy. Zinc-lead-zinc ore extracted from the metal out of late, is the ancient seven kinds of non-ferrous metals (copper, tin, lead, gold, silver, mercury, zinc) in the last one. Zinc metal with blue and white, hardness 2.0, melting point 419.5 ℃, boiling point 911 ℃, heated to 100 ~ 150 ℃, with good pressure resistance, specific gravity of 7.19 after rolling. Zinc can be made with a variety of non-ferrous metal alloy or zinc alloy, most notably zinc and copper, tin, lead, brass composition, etc., can also be composed of aluminum, magnesium, copper and other die-casting alloys. To take into account the value of mining transportation, processing, and other conditions exposed situation, it is important to also consider the issue of the content of harmful substances, is the content of phosphorus pentoxide, exceed the allowable value will increase the difficulty dressing, that increase costs, ore The price will be implicated. Mineral exploitation and comprehensive consideration, comprehensive evaluation, utilization. Lead and zinc prices continue to rise sharply recently on May 10, according to the market price monitoring, Youxi 9400 yuan per ton of lead concentrate slag machine, up 400 yuan, an increase of 4.4% are zinc concentrate 7600 yuan per ton, the chain rose 1400 yuan, up 22.6 percent were electric slag machine maintenance, was sustained upward trend. Mineral prices continued to rise mainly due to: the national launch of non-ferrous metal industry revitalization plan, to ensure smooth operation of non-ferrous metal industry, electric slag machine franchise, speed up industrial restructuring, promote industrial upgrading; domestic car production and sales hit a record high for two consecutive months automotive industry as a whole to further pick up, because lead is the main raw material of car batteries, lead and zinc market prices stimulate increased demand for electric slag machine manufacturers | Baoding Cinder machine | Crawler Cinder machine provided by Gongyi City Xinhua Machinery Factory.
