these deposits formed the basis of australias lead-zinc silver mining industry. resources. lead was the first metal mined in australia at glen osmond in south australia in 1841, after the wheel of a cart being pulled up a rough track accidentally exposed some lead-zinc ore. In 1876, lead-silver ore was discovered and mined at thackaringa, near mining first successfully carried out by native americans brought many of the first white miners to this region of the country. lead-bearing ore existed in such quantity that early mining techniques, while crude, proved successful.open-pit mining is a type of strip mining in which the ore deposit extends very deep in the ground, necessitating the removal of layer upon layer of overburden and ore. In many cases, logging of trees and clear-cutting or burning of vegetation above the ore deposit may precede removal of the overburden. the

History Of Lead Mining Minerals And Mines Foundations
the century was a period which saw cornish mining technology used to deepen some of the mines in search of richer ore deposits. however, as the lead veins narrow with depth, this proved unsuccessful, and attention was switched to resmelting the lead-rich waste slag and slimes left over from previous medieval mining.iron ore mining can be broadly divided into two categories namely manual mining which is employed in small mines and mechanized mining is suitable for large iron ore mines. manual mining method is normally limited to float ores and small mines. mining of reef ore is also being done manually on a small scale. the float ore area is dug up other relations involved in lead ore mining were the vipond, broadwood, bell, calvert, coulson, hewitson, and liddell families, originating primarily from around alston and garrigill and allendale. bit further away, were also the five cochrane brothers who came to australia in the being coal miners and farmers from bamburgh near the coast.
