What Mineral Resources Can Be Found on the Moon?

19-11-2010· Resources like this are commonly found on the Earth. This means that the value of mining on the Moon is potentially not very worthwhile. The costs associated with trying to undertake a mineral mining expedition – especially the high costs associated with traveling through space – make the prospects of mining on the Moon pretty unappealing.

New insights into separating wolframite from calcium

25-05-2021· Wolframite is often associated with calcium bearing minerals such as fluorite (CaF 2) or calcite (CaCO 3), which causes difficulties in enriching wolframite using current collectors. Therefore, developing efficient collector with superb selectivity for the separation of wolframite from calcium bearing minerals is crucial to the extraction of tungsten resources.
