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 Broken Hill in New South Wales, but the mines closed in 1877.

Amongst the above-listed minerals which are mined alongside lead, zinc is found in great quantity and more often than others. Different types of lead ...
This paper summarizes the classification of ore deposits and different beneficiation techniques that are currently employed for the treatment of lead-zinc ore. Froth flotation is the …
Between 1974 and 1986, the Mount Gunson Copper Mine produced, as by-products, ~31 000 t of zinc and 7500 t of lead within a mixed sulphide concentrate derived from 7.5 Mt of Cattlegrid deposit ore. Mineralisation, comprising chalcopyrite, bornite and chalcocite with minor sphalerite and galena, occurs in the upper surface of a palaeo-permafrost ...
In most lead-zinc mines, zinc is higher than lead. Most of the lead-zinc sulfide mine uses preferential flotation technology, "floating lead and zinc-suppressing", which is often reasonable both technically and economically. 2 Lead-zinc oxide ore In the lead-zinc oxide ore, lead is mainly present in the state of leucite and lead bismuth ...
Lead and Zinc Mining in the Dubuque Area by Greg A. Ludvigson and James A. Dockal This small cave, along Catfish Creek valley, is an example of cavern development in an oxidized lead ore deposit and may have been one of Julien Dubuque's "Mines of Spain."

Environmental Impacts of Lead Ore Mining and Smelting. October 2013; Advanced Materials Research 878; ... plants on five lead/zinc mine tailings in Southern China. Restoration Ecology 13, 49-60.
The beneficiation of low-grade oxidized lead and zinc ore from the Lanping mine has attracted extensive interest in the mineral processing field due to the extremely rich resource reserves and the challenge in lead and zinc recovery. This study's objective is to analyze the process mineralogy characteristics and to conduct the flotation optimization of this ore. …
Lead and zinc ores often occur together, and there are a large number of countries that mine and process lead ore, making it among the most widespread metals in terms of primary production …
The Huili orebody, located in Sichuan Province, China, is a complex sulfide-oxide lead and zinc mine. This type of ore has a high oxidation ratio (lead oxidation rate 50%±, zinc oxidation rate 30%±), and contains high percentage (60%±) of gangue minerals with good floatability and the property of being easy to mud.

Lead ore is mainly mined as a byproduct of zinc and. silver. The proven lead ore resource is over 2 billion tonnes, and the reserve volume is about 90 million tonnes.
Complex and non-sulfide lead–zinc ores are difficult to concentrate, but the growing demand for lead and zinc metals necessitated their beneficiation. Froth flotation is practically the most effective method in their beneficiation when optimum flotation conditions are attained. The aim of the current study is to use process mineralogy as a tool to understand the …
