Botswana Mining Review Comprehensive Coverage of the Progress and Achievements in the Mining Sector

Early automotive engines didn’t use any kind of filtration for the oil. It wasn’t until a patent was granted to Ernest Sweetland and George Greenhalgh in 1923 – for their product the “pure oil later” or “Purolator” – that you could buy an automobile with a full-pressure lubrication system. It …

More is not always the right approach when it comes to using oil additives.  In many instances, blending more additive into the oil, does not result in improved performance. Sometimes, adding more additive actually causes the oil’s function to deteriorate.  In other cases, while the performance of the additive doesn’t …

Increasing the percentage of a certain additive may improve one property of an oil, while at the same time degrading another. When the specified concentrations of additives become unbalanced, overall oil quality can be affected. Some additives compete with each other for the same space on a metal surface. For …

By simply including an additive, an inferior base oil cannot be converted into a premium product. It is illogical to use poor-quality oil on a continuing basis, and attempt to overcome its poor lubricating qualities with some special additive. A far better approach is to determine the manufacturer’s recommendation as …

In a move aligned with its ambitious expansion plans, Andrada Mining has chosen to incorporate TOMRA XRT sensor-based sorting technology into its flagship Uis Mine in Namibia. This strategic acquisition includes the addition of pre-concentration circuits aimed at enhancing the mine’s output. The Uis tin mine, one of Namibia’s largest …
