Abstract
This progress report contained seven individual studies. Studies included: the dissolution of asbestos (1332214) minerals in neutral salt solutions; electrooxidation of cinnabar, and the importance of parameters such as salt concentration, ore particle size, current density, treatment rate in amps per ton ore, electrode composition, electrode spacing, and temperature on the mercury (7439976) content of the calcine; the use of a new analytical method based on x-ray emission induced by the passage of energetic protons through mineral samples for the performance of trace metal analyses of asbestos minerals; adsorption of carboxylic groups of ferric-oxide and hematite, in relation to a new class of collectors, the amphoteric surfactants; the correlation between nickel and magnesium dissolution from chrysotile (12001295) in 1 normal hydrochloric-acid and 1 normal acetic-acid solutions; injection of Swiss-Webster-mice in the flank with amosite (12172735) suspended in physiological saline to investigate fiber distribution via the lymphatic system; and injection of Wistar-rats in the thoracic cavity with asbestos samples to study the carcinogenesis of asbestos fibers as related to surface chemistry.
