The problem of ore-bearing potentiality of the strata involves metallogenic theory and ore-search orientation. Studies of the spatial distribution of endogenic Au-Ag polymetallic ore deposits in North Hebei indicated that the strata in which ore deposits occurred range in age from Paleozoic, Proterozoic to Mesozoic. In addition the ore deposits are characterized as being strata-bound in nature. The...
In this paper, the role of pH value on the adsorption of Hg2+ on the laterite from Guizhou Province was studied. The lower pH is unfavorable to the adsorption of Hg2+ whereas the higher pH is favorable to the adsorption of Hg2+. When pH reached a certain value, the amount of Hg2+ adsorption reached the maximum. Then the amount of Hg2+ adsorption was reduced with increasing pH value.
