Manganese deposits of the Cape Peninsula, South Africa by MacGregor, Duncan Graeme

“…From the field data, petrography and chemistry by electron microprobe analysis, it was established that the method of deposition was lateral secretion and the deposits fit into Harrison’s (1998) manganese classification as a Type 1 deposit. Lateral secretion involves the reduction of manganese and iron oxides within the soil profile by acidified rain water, further leaching of oxides as reducing groundwaters flow through regolith and bedrock, and the eventual precipitation as oxides at groundwater seeps and springs. …”

Fine coal beneficiation: comparison study of the separation efficiency of a dense medium cyclone and flat-bottom cyclone by Lumbela, Naledi

“…High levels of NGM in coal impede classifier separation efficiency because NGM particles have low settling rates, which hinder free particle movement during classification. Low-grade coal has a high ash and near-gravity material content, making it economically unviable to beneficiate. …”
