Lead Introduction
Lead is a soft, malleable poor metal. It is also counted as one of the heavy metals. Metallic lead has a bluish-white color after being freshly cut, but it soon tarnishes to a dull grayish color when exposed to air. Lead has a shiny chrome-silver luster when it is melted into a liquid.

Introduction to Lead Mining Industry

Lead ore mining process was always very hard and dangerous work. From the early 1740's until around 1890 mining was usually done by one man holding a chisel while his partner hit it with a sledgehammer. Once a suitable hole was created, gunpowder was placed in the hole, a straw fuse attached and lit. After the explosion when the dust had settled, the men would then break up the rock and the lead mining would be taken to the surface for processing.
The lead mining was taken to the surface by boys as young as 8, dragged out on sleds, for the 'dressing' process. This is where it is separated from the waste materials prior to smelting. Once the lead mining was separated it was washed and then crushed and washed again until it was clean.

Lead Mining Crusher
Lead mining crusher is the essential mining equipment in lead mining mining and lead crushing industry. Most ores contain less than 10% lead, and ores containing as little as 3% lead can be economically exploited. Ores are crushed and concentrated by froth flotation typically to 70% or more. When lead is exploited to the ground, it's should be crushed or grinded for its further application. Lead mining crusher will act as the primary crushing equipment in lead mining crushing plant.

 

Lead Mining Applications
Although southwestern Wisconsin is best known today for its rich farmlands, place names such as Mineral Point and New Diggings evoke an earlier time when local mines produced much of the nation's lead. In the early nineteenth century, Wisconsin lead mining was more promising and attractive to potential settlers than either the fur trade or farming. Lead Ore Extraction potentially quick rewards lured a steady stream of settlers up the Mississippi River and into Grant, Crawford, Iowa, and Lafayette counties in the early nineteenth century. By 1829, more than 4,000 miners worked in southwestern Wisconsin, producing 13 million pounds of lead a year.
Europeans had known of the presence of lead mining in the upper Mississippi since the seventeenth century, and for hundreds of years before that, the Ho-Chunk, Mesquaki (Fox), Sauk, and other Indian tribes had mined its easily accessible lead. French fur trader Nicolas Perrot began actively trading in lead mined by Indians in the 1680s. When the French withdrew from the area in 1760, Indians guarded the mines carefully, revealing their locations only to favored traders such as Julian Dubuque.
Settlement in the region remained slow until a series of treaties between 1804 and 1832 gradually ceded all Indian lands south of the Wisconsin River to the U.S. This coincided with a strong demand for lead, which was widely used in the manufacture of pewter, pipes, weights, paint, and of course, ammunition for the firearms of an expanding U.S. military.
