Copper oxide minerals are important copper resources, which include malachite, azurite,
chrysocolla, cuprite, etc. Flotation is the most widely used method for the enrichment of …

Management of mine wastes (eg, waste rock and tailings) is becoming an increasing global
environmental concern for mining industries around the world. With environmental …

This study examined the efficacy of response surface methodology (RSM) and artificial
neural network (ANN) optimization approaches on barite composition optimization from low …

Annually, millions of tons of lead and silver concentrates are produced using flotation
processes from ores. Xanthates are used as collectors to recover minerals containing lead …

Open-pit mining generates a large volume of waste rocks (WR) that are deposited as
unsaturated piles on the surface. WR are mainly characterised by the high heterogeneity of …

The present study aims at the valorization of useful minerals contained in polymetallic mine
wastes. Ichmoul mine (Batna, Northeastern Algeria) is one of these mines, it was abandoned …

A representative sample of zinc oxide from Dashteh Sefid mine was obtained and then
mineral characterization studies were done. The results of mineralogical analysis showed …

Zarigan mixed oxide-sulfide complex ore (Yazd province, Iran) contains 6.12% Pb, 0.87%
Zn, 47.27% Fe2O3, and 27.18% SiO2. In the present paper, the possibility of lead …

This research work deals with the upgrading of lead in Sabon Layi lead-zinc ore using
gravity and froth flotation beneficiation methods. Analysis of the chemical composition …

Purpose. Galena and barite are the principal minerals of lead and barium respectively. Both
minerals are used extensively in industries because of their distinct properties. In complex …
