Low-grade gold ore may contain very small amounts of gold that are extracted with chemicals that may contain cyanide, cadmium, lead, arsenic and mercury. This often ends up in the environment or in hazarous waste dumps. Gold production is also energy intensive with up to 25 kW·h of electricity used to produce a single gram of gold.

Gold and silver in 30-g samples were determined using fire assay fusion with lead collection followed by atomic absorption spectroscopy (FAA). Samples of 0.25 g were digested in hydrochloric, nitric, perchloric and hydrofluoric acids and the resulting solution was analyzed for copper using FAA. Samples of 1 g were analyzed for carbon and sulphur using a combustion furnace.

Gold doré bars commonly come from two sources; mines or reclamation scrap. Mines almost never excavate pure gold ore. Most ores contain a mixture of gold and other useful base and/or precious metals. Silver for example is one of the precious metals most often found with gold ore, so a doré bar will often be made primarily from these two metals.
