The response of Baban Tsauni (Nigeria) lead-gold ore to gravity separation methods was investigated in this research work. Value addition to run-off mines is always necessary in order to reduce downstream metal extraction costs. Gravity separation methods (the focus of this work) are the cheapest beneficiation methods. This study applied three gravity separation methods: jigging, multi-gravity ...

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...

Th is study aims at studying effect of anaerobic dissimilatory iron (III) reducing bacterial consortium on different phases of iron present in lateritic n ickel ore. Such conversion in lateritic nickel ore are helpful in better recovery of sorbed metal values like Ni and Co by subsequent bioleaching or acid leaching. Here properties of thermally and microbially reduced lateritic nickel ore are ...

In the established technologies, use of classic depressants pyrite, such as lime represents one main problems in flotation gold-bearing copper (Cu) ores. Lime addition leads to depression noble metals - gold (Au) and silver (Ag) that end up tailings. Thus, operator incurs economic losses. The current paper presents research aimed at replacing pyrite ore, bearing silver, classical depressor with...

The Eskay Creek gold-silver mine, located in northwest British Columbia, is an unusually high-grade ore deposit. The mining industry continues to spend more than $2 million each year on exploration for similar deposits in the area. The geologic setting at the minesite is well studied, but large tracts in north-central British Columbia require more detailed surveys to determine if favourable sit...

Biomining is the use of microorganisms to extract metals from sulfide and/or iron-containing ores and mineral concentrates. The iron and sulfide is microbially oxidized to produce ferric iron and sulfuric acid, and these chemicals convert the insoluble sulfides of metals such as copper, nickel and zinc to soluble metal sulfates that can be readily recovered from solution. Although gold is inert...
