Sulfide gold ores will be filled with shiny flecks, but not all of them will be gold. Gold and fool's gold can form alongside each other, making this kind of ore deceptively chock full of shiny material. Blue clay gold ore is found in, you guessed it, blue clay. It will be mixed up with black sand and tiny pieces of quartz.

Gold ore is an ore that can be obtained from gold rocks, gold deposits, and buffalkors. Gold rocks naturally generate on the Buffalkor Island,Emerald Mines, and the Diamond Mines. Mining a gold rock yields 2 - 3 gold ore per stage, resulting in a total of 4 - 6 gold ore. There's also a 10% chance the rock drops crystallized gold. Gold rocks used to spawn on Wizard Island before the …

The use of thiosulfate to extract gold from refractory ores is promising because of its non-toxicity and high selectivity. Sulfide minerals (i.e., pyrite, arsenopyrite, chalcopyrite), major gold carriers in refractory gold ores, however, hinder gold extraction due to the high consumption of a lixiviant. In this study, a new method to improve gold extraction from sulfide bearing gold …
