Overview Flotation is the most flexible and adaptable mineral beneficiation technique. Mineral separation by flotation works on physicochemical surface properties of valuable and unwanted gangue minerals. It is being continuously modified for low-grade complex sulfide ores like lead-zinc, leadzinc-copper, nickel-platinum-gold, tin, fluorite, phosphate, fine coal and iron ore at a lower cost with better recovery.

In a paper published in Nature Communications, the researchers […]

Greenfields exploration is normally conceptual, relying on the predictive power of the ore genesis models, to search for the mineral resource in an unexplored virgin ground. Brownfields exploration is conducted within geological terrains which are closer to known ore deposits. Brownfields is less risky, as the geology is better understood and the exploration methodology is […]

Introduction The excavation or drilling in rocks becomes extremely complicated when working in confined spaces and if you need to drill holes with large diameters. Often the length and diameter of these perforations becomes impracticable due to the cost of time and labor. In view of these problems, a simple, compact and really solution was […]

The Tau Tona Gold mine in South Africa was extended to a depth of 3.9km in 2008, making it the world’s deepest mine at that time. The name TauTona means ‘great lion’ in Setswana (“TauTona Gold Mine, Anglo Gold, South Africa,” n.d.). The mine was located at on the West Wits line, south of Carletonville, […]
