To separate one base metal mineral from another by flotation, it is indispensable to identify chemical reagents that specifically interact with the surface metal sites of one mineral or a group of minerals. This work studies the interactions of chelating collectors which offer the best potential for collecting abilities and mineral specificity with a typical refractory oxide mineral (malachite)...

In this study, 115 samples taken from the stream sediments were analyzed for concentrations of As, Co, Cr, Cu, Ni, Pb, W, Zn, Au, Ba, Fe, Mn, Sr, Ti, U, V and Zr. In order to outline mineralization-derived stream sediments, various mapping techniques including fuzzy factor score, geochemical halos and fractal model were used. Based on these models, concentrations of Co, Cr, Ni, Zn, Ba, Fe, Mn, ...

This papaer reports on mapping in a portion of NTS 94G/4W (Mt. McCusker west half), conducted during the month of July 1998 (Figure 1). This area, only accessible by air, lies 80 kilometres due west of the small settlement of Pink Mountain, 151 kilometres north of Fort St. John on Highway 97. The mapping program is part of the Central Foreland NATMAP Project, led by Mike Cecile of the Geologica...
