Easy-to-Process Ores ; Ores with fewer impurities and a higher concentration of free-milling gold can be processed using straightforward methods like gravity separation and cyanidation. Refractory Ores; Ores containing sulphides or other complex minerals can trap gold, making extraction more challenging.

Gold ores are commonly classified by the metallurgist into two major categories: free-milling and refractory ores. Typically, free-milling ores are defined as those where over 90% of gold can be …
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 …
First of all, if you want to farm for Silver and Gold Ores, try to stay within the first 30 floors. The Baddies will start getting pretty annoying after floor 30 and they become pretty hard to dodge.
