Research on Rationalization for Cyanidation Reagent

Potatoes: Source of Laboratory Reagent for Human Platelets Research

Irish potatoes is rich in carbohydrate, with varied glucose levels. It is also a very good source of apyrase, an enzyme used for platelet storage. The aim of this study was to explore Irish potatoes as an easily available source for apyrase extraction and purification. Apyrase was extracted from 5 Kg of Irish potatoes. Platelets were derived from 5-10 ml of human whole blood and G6PD activity w...

Electrooxidation as a Pretreatment Process Before Cyanidation

Copper and Cyanide Recovery in Cyanidation Effluents

Cyanidation is the main process for gold and silver recovery from its ores. In this study, a process is proposed to recover copper and cyanide from barren solutions from the Merrill-Crowe cementation process with zinc dust. This technology is based on inducing nucleated precipitation of copper and silver in a serpentine reactor, using sodium sulfide as the precipitator, and sulfuric acid for pH...

Categorifying Rationalization

We solve a problem proposed by Khovanov by constructing, for any set of primes S, a triangulated category (in fact a stable∞-category) whose Grothendieck group is S−1Z. More generally, for any exact∞-category E, we construct an exact∞-category S−1E of equivariant sheaves on the Cantor space with respect to an action of a dense subgroup of the circle. We show that this∞-category is precisely the...
