Copper slag is a hard material produced from smelting copper-bearing ores. Over the years, research has prioritized utilizing as secondary source of base metals. This paper focuses on grinding/milling copper collected BCL Mine in Botswana to obtain maximum amount desired size class with minimal energy consumption. will then be followed by an integrated flotation and leaching approach recover co...

Abstract Mines result in land use and cover (LULC) change due to degradation of natural resources establishment new infrastructure for ore extraction beneficiation. The present study was carried out to, with objectives, (1) characterize LULC (from 1975 2017) Khetri copper mine region, (2) spatial distribution pollution indices (3) spectral response elemental concentration soil groundwater using...

Two nanofiltration membranes, a Dow NF 270 polyamide thin film and a TriSep TS 80 polyamide thin film, were investigated for their retention of ionic species when filtering mine influenced water streams at a range of acidic pH values. The functional iso-electric point of the membranes, characterized by changes in retention over a small pH range, were examined by filtering solutions of sodium su...

The Richmond Mine of the Iron Mountain copper deposit contains some of the most acid mine waters ever reported. Values of pH have been measured as low as -3.6, combined metal concentrations as high as 200 g/liter, and sulfate concentrations as high as 760 g/liter. Copious quantities of soluble metal sulfate salts such as melanterite, chalcanthite, coquimbite, rhomboclase, voltaite, copiapite, a...

Soils around mining sites play a significant role in the transport and control of heavy metals in the environment. Therefore, understanding the adsorption properties of soil is essential in solving pollution problems. The objective of this paper was to study Zn(II) adsorption onto Sarcheshmeh copper mine soils. The adsorption isotherms of Zn(II) were studied. The Langmuir isotherm indicated an ...
