Evaluation of stucco binder for agglomeration in the heap

Although the cement has been used in precious metal ore agglomeration (gold ores) for heap leaching from the 1980s, very few, if any, copper heap leaching operations add any binder to the sulfuric acid solution, possibly because of the binder cost, large consumption and curing issues, and limited selection of acid tolerant and microbial resistant binders (McClelland, 1988; Bouffard, 2005)....
