In this paper, we evaluate chemical weathering and its climatic significance in different periods (pre- and post-industrialization) in a basin impacted by 500 years of mining activities. We consider the geochemical and mineralogical composition of stream sediments and overbank deposits from the Guanajuato River Basin (GRB) in central …

Beneficiation by Flotation of feldspar is well established. It is a simple matter by flotation to remove the contaminating impurities and keep the alumina (Al2O3) content at 19% even on low grade feldspar ores. Dry recovery methods are economically limited to about 17% Al2O3. The problem in feldspar flotation is to recover slime free granular ...
