Wang et al 2018 examined the development of an ultra high performance concrete UHPC sample using a combination of lead zinc mine tailings Lead zinc mine tailings by weight were used as a substitute for 10 20 30 and 40% of cement and their effect on fresh and hardened UHPC behaviors was studied
The examined mine waste contains amounts of lead and zinc which can be potentially recovered by developing a hydrometallurgical method which is selective for zinc and lead with respect to iron
Energy and Environmental Profile of the Mining Industry 6 Lead and Zinc Lead and zinc ores are usually found together with gold and silver A lead zinc ore may also contain lead sulfide zinc sulfide iron sulfide iron carbonate and quartz When zinc and lead sulfides are present in profitable amounts they are regarded as ore minerals
The PMF indicated that there were five sources namely pyrite mines lead zinc mines natural sources of basalt and carbonatite and agricultural activities; the risk contribution ratios were % % % % and % respectively
world class lead/zinc subdistricts surrounding the St Francois Mountains fig 1 the Old Lead Belt; the Mine La Motte Fredericktown which also produced nickel copper silver and cobalt; and the Viburnum Trend currently 2008 producing lead zinc copper and silver The Old Lead Belt is north of

Chenzhou lead/zinc mine is located about 10 km east of Chenzhou city Hunan Province However the ratios of the other elements are very low times at GYB At JTC where the mining waste spills were cleaned Cd ratio is still the highest among all the considered elements However the ratio for the other elements is lower than 1
Non sulfide zinc lead deposits are one of the important sources of lead zinc and other metals globally [1 2 3] In the early 20th century lead and zinc were primarily sourced from sulfide ores [] In recent years the development of beneficiation technologies has enabled the reutilization of non sulfide zinc lead resources particularly those dominated by smithsonite [5 6]
1 Solid Waste and Chemicals Management Center Ministry of Ecology and Environment Beijing China; 2 MOE Key Laboratory of Soft Soils and Geo environmental Engineering Zhejiang University Hangzhou China; China holds large scale lead zinc mineral resources; however mining activities often cause severe contamination by heavy metals This
In November 2016 the total metal concentrations in nine representative locations in lead Pb zinc Zn mining areas located in Guangdong Province South China were determined experimentally by flame atomic absorption spectrometer The results indicated that the paddy soils were heavily contaminated with Cd mg kg−1 Pb mg kg−1
This article reviews studies published in the past 10 years on the environmental and human health consequences of lead/zinc mineral exploitation in China and concludes that lead Pb and cadmium Cd are the main pollutants and are associated with human health effects Mining and smelting are important economic activities However mining related
The study area is known for abundant lead zinc mineralization and igneous activities Chukwu and Obiora 2014 Chukwu and Obiora 2018 and lead zinc mining has lasted for more than nine decades and presently mining and quarrying activities are still active in the area The mines have been grouped into two namely Green Field metal mines

The study of the spatial distribution of heavy metal accumulation in mining soil and the identification of pollution sources are key issues in the prevention and control of heavy metal pollution in mining soil [6 7] China is one of the largest producers and consumers of lead and zinc in the world [] Large scale mining of lead and zinc mines has stimulated the
Tailings dams in mining areas frequently experience the phenomenon of haphazard dumping and stacking of a large amount of tailings waste Under the influence of surface runoff and groundwater infiltration heavy metals from tailings waste can migrate to the surrounding areas and underground soil resulting in extensive heavy metal pollution To
