The impact of Mn in manganese waste rocks and electrolytic manganese residues on the growth of capsicum was studied via pot experiments. The product yield and manganese nutrition were mainly evaluated in this study. The results showed that the ingredients of manganese tailings were beneficial to the increase of chlorophyll contents in the capsicum.

Characteristics of silicate glasses derived from vitrification of manganese crust tailings. ... the potential weight loss from having approximately 25 wt% MnO in the 4-21 glass mixture along with a nominal CaO content are considered to be offset by the possible improvement in alkaline durability due to the presence of MnO.
Manganese can be released to water by discharge from industrial facilities or as leachate from landfills and soils. Land disposal of manganese-containing wastes is the principal source of manganese releases to soil [29]. Sea disposal of mine tailings and liquor is reported to be a not negligible source of manganese to the marine environment [18].

Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes. These processes also have an impact on the atmosphere from the emissions of carbon which have ...

• Significant potential environmental risks are associated with extreme natural events and failures in management practices. Extreme natural events (e.g., hurricanes, earthquakes, intense rainfall events, drought) have the potential to lead to the release of contaminants if facilities are not designed and constructed to withstand such events, or fail to perform as designed.

A TSF is a highly engineered structure which consists of one or more tailings dams, with embankments designed to permanently store the tailings. Every individual dam is unique and is designed, built and operated to specifications that are tailored to the physical nature of the tailings material itself, and a number of other factors.
Jan 01, 2012 · However, the tailings at the Pronto waste management area near Elliot Lake, Ontario, covered with 30 cm of pulp and paper biosolids about 15 yr ago, maintained that thickness. The carbon loss due to degradation is potentially being balanced by carbon inputs from both roots and litter fall from the perennial vegetation.
