samples of the waste rock obtained from marofengin south africa ground 60, 70 and 80% passing 75µm were leached with cyanide in bottle roll tests. the results obtained showed that the percentage gold dissolution depends more on the ore size consists than on the cyanide concentration with the highest average dissolution rates of 88.75, 94.34 and 95.90% found at 600, 500 and 500 ppm, for 60, 70 a...

Herein, we report on the development of a waste minimization/valorization methodology applied to representative benchmark Sonogashira cross-coupling reaction performed in continuous-flow reactor, featuring downstream membrane organic/aqueous separator recover medium and products with minimal waste. The protocol is based use biomass waste-derived heterogeneous Pd-based catalyst, which obtained f...
