[29 CFR 1910.1025(g)(2)(vii)] Removal of lead from protective clothing or equipment by blowing, shaking, or any other means which disperses lead into the air is prohibited.
The safe treatment of smelter ash with high arsenic is of great importance both for environmental protection and resource comprehensive utilization. In this study, arsenic removal from lead-zinc smelter ash by NaOH-H 2 O 2 leaching was studied. The effects of different operating parameters on the leaching rate of arsenic and leaching kinetics ...
Surface disposal of mill tailings and fly ash is a major concern for many countries, as it pollutes the environment including air, water, and soil. Paste backfilling is an emerging mine backfilling technique, wherein the industrial wastes such as mill tailings, fly ash and blast furnace slag are backfilled inside the stopes. This study examines the physico-chemical characteristics …
