Enzymatic Pre-Treatment of Carbonaceous Matter in Preg ...
The bio-treatment of double refractory gold ores (DRGO) to reduce preg-robbing needs to account for the heterogeneity of the ore so as to acquire a much more complete picture of the system. To this end, the effects of ferrous ion additives on the degradation of powdered activated carbon (PAC) by cell-free spent medium (CFSM) was studied. Au(CN)2- adsorption and Raman spectrometric results ...
is gold ore ferrous
Ferrous Ore . Highlights Two gold ores were subjected to iodide/iodine leaching. The carbonaceous ore showed only 20% gold extraction. Gold extraction from the oxide ore reached 89% in 24 h. A power law rate equation was applied to model the gold extraction kinetics. Gold leaching rate was first order with respect to tri-iodide concentration.
Can Metal Detectors Tell The Difference Between Metals?
For once, gold within the ground does not occur in the form of nice, big nuggets. In fact, it is usually in particulate form and surrounded by soil containing iron ore. Gold detectors use discrimination to detect gold and ignore other metals. Other than that, it all boils down to the technology:PI or VLF.

Roasting (metallurgy) - Wikipedia
Roasting is a process of heating a sulfide ore to a high temperature in the presence of air. It is a step in the processing of certain ores.More specifically, roasting is often a metallurgical process involving gas–solid reactions at elevated temperatures with the goal of purifying the metal component(s). Often before roasting, the ore has already been partially purified, e.g. by froth ...
