This has hurt commodity prices for base metals such as copper, aluminum, nickel and zinc, which are driven by industrial demand. Precious metal prices, such as gold and silver, have generally held up better than base metals, however, day-to-day prices, particularly for gold (which is viewed as a hedge against economic uncertainty), are extremely volatile.

Heavy duty slurry pumps with agitator

Toyo, the world renowned Japanese manufacturer of pumps for heavy and abrasive slurries, has been present for many years in Africa, notably in mining applications.

This manufacturer has developed a large range of pumps with a unique built in agitator. The patented agitator lifts the sediments, creates a homogenous mixture and allows stirring up of solids that have settled in the liquid. The design of the Toyo pump makes continuous pumping of high concentration of abrasive materials possible (up to 70% in weight). It is exactly what is needed for pumping solids in mines.

Appropriate Process Technologies – new heights for mineral processing

Small mining conjures up reclusive old timers in days gone by, or perhaps hoards of clay covered artisanals digging up river courses today. But there is a whole new movement happening, a new fresh energy growing from within this sector looking to be recognised and acknowledged for what it is – the appropriate way to utilise these vast, unconventional resources. Commonly known as small scale mining or artisanal mining this sector has been in the wings of mining for ages.
