Introduction The live donor nephrectomy is an unusual surgical procedure as it is performed on healthy individuals. It is important to make the procedure as safe as possible without compromising the health of the donor and graft function. Justificati

Kinetic studies on the flotation of a fine-grained complex lead-zinc ore showed that sphalerite exhibits considerable floatability during the later stages of galena flotation, causing a loss of zinc to lead concentrate. The lead concentrates obtained

Diethylenetriamine (DETA) is a selective depressant for nickeliferous pyrrhotite during pentlandite flotation. Laboratory flotation tests conducted on ore and process samples showed that pyrrhotite rejection is greatly improved by small additions of

The species formed by the anodic oxidation of ethyl xanthate at gold electrodes has been investigated using an ex situ Fourier transform infrared (FTIR) spectroscopic technique to distinguish between chemisorbed ethyl xanthate and diethyl dixanthogen

The interaction of ethyl xanthate with copper electrodes has been investigated by UV-Vis and ex situ FTIR spectroscopies. Xanthate was found to be abstracted from solution in the potential region in which previous studies indicated xanthate to be che

The characteristics of the interaction of ethyl xanthate with silver—gold alloys have been compared with those of the pure component metals. Voltammograms for silver and silver—gold alloys (50:50 and 20:80 (wt.%)) in the presence of ethyl xanthat

The fundamental mechanisms of dicresyl monothiophosphate (DCMTP) adsorption on gold, silver and gold-silver alloys have been investigated in the present work. The monothiophosphates are obtained by replacing one of the sulfur donors in the functional

Eh-pH diagrams have been constructed for chalcocite in the presence of xanthate. Stability regions for cuprous xanthate have been shown to be dependent on the sulfur oxidation state. As oxidation proceeded from elemental sulfur to sulfate, the copper
