Lithium – Doing you a power of good!

Lithium is a chemical element with the symbol Li. It is not found in nature in its pure form but most commonly in igneous rock as well as lithium rich brine in salt lakes.  It was first discovered in 1817 by Swedish chemist Johan August Arfwedson when he analysed petalite ore, but it took a number of scientists to work out how to extract this soft, grey-white, alkaline metal.  Australia is the world’s leading producer of lithium, followed by Chile and Argentina.

Reduce Operating Costs through Effective Bulk Dozer Push

In an open cut mine, bulk dozer push can be one of the most cost-effective methods of moving overburden. Under the right application, the unit cost of dozer push sits somewhere between a dragline and truck/shovel excavation. So, if geotechnical conditions are favourable and the dozer fleet is sufficient, dozer push should be considered to replace some of the truck/shovel prime. Dozer push can also be used to replace dragline prime. This is because it can speed up the linear progression of the dragline – which in many cases will lower the dragline unit cost rate and increase coal uncovery.
