The gold is in liquid form in the HCL. Add sodium metabisulphate to force the gold to become metallic gold again. The sodium metabisulphate lowers the pH of the solution, turning the gold liquid into gold powder. Filter the water again using a fine gold filter and dump the water into another bucket and not onto the ground or down the drain.
Abstract: This paper presents a study to obtain sulphide as byproducts of a concentrated cleaner of gold generated from the flotation process of sulphide gold ore of mine Morro do Ouro. Chemical analysis of the concentrated of gold showed a content of approximately % S, in the form of a bulk sulphides. The liberation of the sulphides was
Sulfide ores, such as chalcopyrite, sphaelerite, galena, and pyrrhotite, and mixtures of these ores have historically been found with micron size gold particles included in them. This generally involves frother, several collectors (promoters) and possibly some modifying or depressing agents as well.
Sulphide Gold When properly characterised, sulphide complex gold ores can be efficiently processed using a Gekko flowsheet design. When gold is associated with sulphides, it can be either fully encapsulated by the sulphide particle or partially liberated, exposed on the edge of the sulphide mineral.

Metallic sulfide mining (aka hard rock mining) is the practice of extracting metals such as nickel, gold and copper from a sulfiderich ore body. Sulfides are a geologic byproduct of mining in this area, and by exposing sulfides to the air and water in our atmosphere, sulfuric acid can be created — threatening to poison the nearby water ...
Mineralisation is characterised by notable quantities of coarse gold (>80% +100micron gold) and very coarse gold (locally >50% +1,000micron gold) hosted in the quartz veins. A high nugget effect is observed, where grades over a few metres may reach 50 g/t Au or higher, but reduce to a few g/t Au out of the high grade.
