The study determined the bond work index of Begaga gold mineral deposit Zamfara State Nigeria using Berry and Bruce modified method. Sample was sourced random sampling Reference (Granite) known weight 15.13Kwh/ton ground for thirty minutes at a particular speed power consumed from rating ball mill. An identical Bagega whose to be in same mill under condition as that reference mineral. Size anal...

Drawing on recent experimental and commercial developments, this review reappraises potential substitute leach reagents for cyanide in the gold mining sector. In addition to extraction, application of these processing, pre-treatment purification stages is explored. The main objective here discuss how extraction process can be more sustainable, with a view developing greener leaching reagents.

Abstract Cyanidation has been considered an effective process for extracting gold from gold-bearing ores over 100 years. However, this also several disadvantages including it being toxic, inefficient, and unsuitable leaching carbonaceous containing organic inorganic carbons. Moreover, is not feasible the extraction of refractory , which are increasingly used.Therefore, there urgent need to find...

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.

the dehbid magnetite deposit is located in northeastern part of fars province, in the southern border of sanandaj-sirjan metamorphic zone. the mineralization occurred as veins and lenses along nw-se faults. the ores are mainly hosted in silicified dolomite of early mesozoic (triassic). mineralogical studies show that the ores are dominated by magnetite and minor hematite with massive texture oc...
