Because of their low grades in critical metals such as Light Rare Earth Elements (LREE) or
Sn, rare-metal granites are not considered as economic for metal recovery but, when …

This is the last in a series of papers addressing the by-product potential of Light Rare-Earth
Elements (LREE, La, Ce, Nd) and rare-metals (Sn, Nb, W) within the St Austell kaolin …

This paper, which is the second in a series of three, follows a previous study that showed
that Light Rare Earth Elements (LREE), hosted in monazite and rare-metals (Sn, Nb, W) …

The strategic importance of tantalum and its scarcity in Europe makes its recovery from low
grade deposits and tailings interesting. In Penouta, the contents of Ta and Sn in old tailings …

Due to the rising pressure from governmental regulations, the water recycling rate has
increased significantly in mining operations over the last decades, resulting in a high …

The dynamicity and variability in terms of quality of recycled mining process water (PW)
brings challenges in the recovery and the quality of the final products. By turning water …

This paper describes of three things. First, the Kriging estimation on gold grade which is
distributed in the vein. The empirical variogram method based on Matheron classical and …

Whereas a classical tool from the Theory of Sampling (TOS), variographic analysis, can
address practical situations with multiple variables, its application has very often been …

A small polymetallic mining operation intended to evaluate the potential for upgrading its
mineral processing plant by adding a new metal recovery line at some strategic point in the …

Whereas a classical tool from the Theory of Sampling (TOS), variographic analysis, can
