Other articles where Refractory ore is discussed: gold processing: Extraction from refractory ores: Many gold-bearing ores and concentrates are not readily amenable to cyanidation, owing to the presence of substances that consume the cyanide reagent before it can dissolve the gold, preferentially adsorb the gold as it dissolves (a phenomenon called preg-robbing), or completely surround the

The principal gold minerals that affect the processing of gold ores are native gold, electrum, Au-Ag tellurides, aurostibite, maldonite, and auricupride. In addition, submicroscopic (solid solution) gold, principally in arsenopyrite and pyrite, is also important. The main causes of refractory gold ores are submicroscopic gold, the Au-Ag tellurides, and very fine-grained gold (<10 µm) locked

How to Recognize Hard Rock Gold Ores. September 2022 by Chris Ralph. I regularly get inquiries along the line of: "Hey, I found this rock, and I think it might be gold ore. How can I tell?" Prospectors are always on the lookout for gold-bearing rocks that may be the source of any nearby placer gold.

Abstract: Gold ores associated with carbonaceous matter present several difficulties in their extraction due to the ability of this matter to adsorb the aurocyanide complex from gold pregnant solutions, resulting in low extractions by direct cyanidation. This phenomenon is known as preg-robbing. In the present work, a process to effectively recover Au from a highly carbonaceous

If you are looking to extract gold from refractory low-grade ores, we are introducing a game-changer to the entire gold mining industry. Your reserves containing refractory gold considered below the cut-off grade are not considered reserves because the cost of extracting it using pressure oxidation and bioleaching is too high. In the future, this is likely to change. We have
