To solve the problem of treating and leaching a clay ore in which the gold was finely disseminated, the author was able to suggest a unique method which he had seen described twenty-five years previously in a paper, "Occurrence and Treatment of Gold Ore at Bidi, Sarawak, Borneo," by T. C. Scrutton, which appeared in Trans. 15, I. M. M., 1905-1906, in which clay ore was treated by leaching ...
Clay minerals are hydrous aluminium phyllosilicates, sometimes with variable amounts of iron, magnesium, alkali metals, alkaline earths, and other cations found on or near some planetary surfaces. Clay minerals form in the presence of water and have been important to life, and many theories of abiogenesis involve them.

Industrial Mineral Resources of Zambia Clive Mitchell, British Geological Survey, UK & Boniface Muibeya, Geological Survey Department, Zambia Abstract Zambia has for many years been heavily dependent upon the mining of copper which, combined with cobalt production, represents over 98% of mineral sales and 75% of export earnings (1997 figures).
Zambia's mineral industry is expected to become more stable in the coming years and recover from the global economic crisis that hit the country in late 2008 and early 2009. Further development of the country's mineral resources is expected in the near future based on the current exploration of uranium, manganese and nickel.
• Primary minerals: present in original rock from which soil is formed. These occur predominantly in sand and silt fractions, and are weathering resistant (quartz, feldspars); • Secondary minerals: formed by decomposition of primary minerals, and their subsequent weathering and recomposition into new ones (clay minerals).
