Geosynthetic clay liners (GCLs) have become a suitable substitute for compacted used prevention of leachate percolation from landfills and tailings dams into the groundwater system. The characteristics most bentonites is improved through process activation by mixing with soda ash (Na2CO3). This paper presents investigation results suitability Imerys Mine in South Africa use GCLs. Both activated...

metals used in everyday life are produced from ores occurring in the earth’s crust. geological processes are known to concentrate minerals to form ores of economic value. mineral processing engineers concentrate these ores by mechanical and physico-chemical methods while the extractive metallurgist extracts the metals by chemical means.

Ore blending is an essential part of daily work in the concentrator. Qualified ore dressing products can make more smoothly. The existing modeling usually only considers quality and ignores effect on dressing. This research proposes method based beneficiation concentrate. relationship between properties total concentrate recovery fitted by ABC-BP neural network algorithm, taken as optimization ...

The rapid depletion of high-grade rare earth elements (REE) resources implies that future supplies may be augmented with low-grade ores, tailings, and other unconventional to meet cut-off grades and, subsequently, supply demands. This paper presents an amalgamation studies conducted on selected complex iron-oxide-silicate-rich the overall aim developing efficacious methods associated process mi...

Today's level of integrated use minerals and beneficiation wastes in Ukraine, particular, at the Kryvbas GOK, is unsatisfactory, as it generally allowing production additional types construction products. The volume mining growing, but only a small percentage extracted transferred to finished product. residue form waste returned environment, polluting it. reason for this lack technology mineral...
