The invention relates to a method for recovering gold from a sulphidic concentrate, particularly one containing arsenopyrite and/or pyrite, hydrometallurgically. The concentrate is first subjected to leaching with a concentrated solution of alkali chloride and copper (II) chloride, by means of which the copper minerals and some of the gold in the concentrate are made to dissolve.

How to Tell If Gold is Real with Vinegar Treasure Pursuits

Gold is unaffected by vinegar because it is a stable metal and will not react with oxygen. That means it will not change color, develop crystals, or disintegrate. If the sample is iron pyrite (Fool's Gold) or chalcopyrite, it may remain the color of gold, but will begin to form crystals while it is submerged.
