19/08/2016 · A mine's key operational objective – to constantly feed ore to surface mills – means that the demands on both men and machines, who work against the clock, are extreme. "Mostly, mines will buy items such as chain hoists except when there are specific shortterm projects – such as a plant shutdown. In this instance, renting Unilift lifting hoists conserves valuable capital, and gives ...
The geological conditions create new challenges in your copper mine. Declining ore grades mean less metal production for each ton processed. And as you have to dig deeper and into harder rock you face longer haulage distances and increased wear of your equipment which translates into higher operational costs. To remain productive, you need endurable and reliable equipment that increases your ...

Recent research has found that mining for copper took place during the Bronze Age around the Great Orme and Cwm Ystwyth, possibly also at Llanymynech. Originally these would have been surface excavations but they soon had to follow the deposits underground as the ore became exhausted. Tools were very primitive and consisted of stone hammers and bone/antler picks. It was metals that attracted ...
