The tailings produced during the lead-zinc mining process contain heavy metal ions such as lead, zinc, and reduces the quality of life of the residents. Security risks [1-4]. Lead-zinc tailings have good burnability and chemical characteristics similar to those of cement and clay. Therefore, the use of lead-zinc tailings to make
Identification of Priority Pollutants and Key Factors
2023年3月11日 The key factors affecting environmental risks of lead-zinc mine tailing sites were identified using the random forest algorithm. Four types of hydrological settings were classified. Pb/Zn/As/Cd/Sb, Fe/Pb/As/Co/Cd, and nitrate/iodide/As/Pb/Cd are identified as priority pollutants of leach liquor, soil, and groundwater, respectively. The
Recycling Lead–Zinc Tailings for Cemented Paste Backfill
2019年10月14日 This study demonstrates the feasibility of recycling lead–zinc tailing (LZT) as a cemented paste backfill (CPB) by considering the mechanical properties and environmental effects, thus providing an approach for safe and environmentally friendly treatment of LZT. First, the mechanical properties of CPB samples were tested. When
Primary Exploration, Mining and Metal Supply Scenario
For instance, datasets have been developed for energy use and greenhouse gas emissions of mining operations (Koppelaar and Koppelaar, 2016; Mudd, 2010; Northey et al., 2013), water use of mining operations (Northey et al., 2019), land-use changes associated with mine development and mine-site infrastructure (Maus et al., 2020; Werner et al
Top 5 Zinc Miners To Consider Seeking Alpha
2017年6月15日 The main reason I like Trevali Mining is that they are basically a pure play zinc miner (with some silver and lead) and they are rapidly increasing zinc production from 45,000t zinc concentrate in
Revegetation of Pb/Zn Mine Tailings, Guangdong
2000年3月1日 The Lechang lead/zinc mine is located in the north part of Guangdong Province, southern China. The tailings residue from the extraction of lead/zinc ores was permanently stored in tailings ponds, which required revegetation to reduce the environmental impact. A field study was, therefore, conducted to evaluate the effects of
Environmental Impacts of Lead Ore Mining and Smelting
Present day lead pollution is an environmental hazard of global proportions. A correct determination of natural lead levels is very important in order to evaluate anthropogenic lead contributions. In this , the impact of mining and smelting of lead metal ores on environmental quality is described. Globally mines produce large amounts of waste
