We examined greenhouse gas (GHG) production upon the addition of ammonium and phosphate to mature fine tailing (MFT) samples from Alberta’s Pond 2/3 (at 5 and 15 m) and Pond 7 (12.5 m) in microcosm studies. The methane production rate in unamended

Thiocyanate (SCN-) is a promising alternative to cyanide as a lixiviant for gold extraction and is 1000 times less toxic than cyanide. In this study, the following leaching parameters were tested to optimize the gold recovery for the first time from

The production of short-chain-length polyhydroxyalkanoates (scl-PHAs) in a sugarcane biorefinery setting has been demonstrated to be an effective strategy to reduce production costs. Medium-chain-length PHA (mcl-PHA) have elastomeric properties and a

The effects of carboxylation (via mercaptoundecanoic acid) on colloidal properties of medium-chain-length poly(3-hydroxyalkanoate) (mcl-PHA) latexes were studied. Non-ionic surfactants tested at 0.4% solids of 11 mol% carboxylated mcl-PHA produced si

Greater than 65% of canola and high-oleic soy oil fatty acids is oleic acid, which is readily converted to nonanoic (NA) and azelaic (AzA) acids by ozonolysis. NA is an excellent substrate for medium-chain-length polyhydroxyalkanoate (mcl-PHA) produc

Gold recovery from limited global resources has gained increasing attention due to a growing demand for gold and heightened social awareness of the high toxicity and the environmental threat of traditional cyanidation. This has led to the development

Thiocyanate is among the most promising alternative gold lixiviants for gold leaching and has not been extensively covered in the literature. Thiocyanate is 1000 times less toxic than cyanide and is a very strong gold leaching lixiviant. This review
