Abstract (en)
[origin: WO2019000091A1] This invention relates to stabilization and/or solidification of hazardous materials which might be generated by activities like mining, milling or smelting industrial operations, such as arsenical wastes (such as scorodite, arsenic sulfides, calcium arsenates or arsenites, mixed calcium arsenates-phosphates, ferrous arsenate, ferric arsenite, or arsenic trioxide), antimony, mercury or selenium-containing wastes through the encapsulation of said arsenical wastes in the mineralized products of hydrolyzed aluminum gels created through the partial neutralization of A1(SO4)1.5 by a carbonate.
