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
Mining lead 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.
Zenith is a professional lead mining crusher manufacturer in lead mining industry. We can supply many lead mining crushers such as lead jaw crusher, lead impact crusher, lead cone crusher, lead mobile crusher and so on. Metallic lead that results from the roasting and blast furnace processes still contains significant contaminants of arsenic, antimony, bismuth, zinc, copper, silver, and gold. Lead mining crushers are used widely in such ore curshing industry. Since the establishment, Zenith has grown to become the largest crusher and screening equipment dealer in the China. So, if you want some lead mining mining equipments or lead crushing machines, you can contact us easily according email: firstname.lastname@example.org.
Lead Mining Crusher Working Details
Jaw crusher for lead mining: Jaw crusher is used in primary crushing station. Lead ore jaw crusher can crush lead mining into small sizes. Thus, these small lead mining can enter into the lead mining mill such as ball mill and vertical mill for grinding.
Lead ore impact crusher is generally used after jaw crusher, and can crush hard stones, not only the lead mining, but also other ores such as copper, bauxite, gold, Kaolinite, manganese etc.
Lead hammer crushers are widely used in small quarries with small capacities. That's because in such situation, the cost and the difficulty of changing and maintaining worn hammers are more acceptable to the quarry owners. However, once the quarry owners want to enhance the capacity to above 50-60t/h by one crushing plant, hammer crushers are no longer suitable. Using hammer crusher to do a big crushing work will lead to a passive situation of high consuming cost and frequent maintenance.
Lead cone crusher is the most common fine crusher, and usually used as final crushing machine. Lead ore cone crusher has four types such as spring cone crusher, CS cne crusher, hydraulic cone crusher, hcs90 cone crusher.
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. Its 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.
Miners who moved to the area in the 1820s and 1830s wasted little time in constructing shelters. Some simply burrowed holes into hillsides, earning miners the nickname "badgers." The tools and techniques involved in lead mining in these early years were relatively simple and inexpensive, allowing lucky miners to strike it rich with little personal expense.
Many of the first miners came to Wisconsin from Missouri, which had experienced a similar lead boom a few years earlier. Communities sprang up quickly around the mines, as other industries and businesses were founded to serve the residents that mining attracted. In the 1830s, experienced miners began arriving from Cornwall in southwestern England. The Cornish settled primarily in Mineral Point and constructed small, limestone homes similar to those they had left in England.
For those who remained, mining often became a part-time supplement to farming. Some men began to mine for zinc, and for a few years in the late nineteenth century, Mineral Point had the largest zinc smelting facility in the world. With mining restricted to only the most profitable localities by 1850, more than 90 percent of the land was free for farming. By 1860, the former lead mining region of southwestern Wisconsin had become recognized as one of the best agricultural areas in the state.
