Smelting of gold could be immediately followed up with refining. These largely depends on what and where the gold will be put to use. Refining of gold is simply the removal of fine impurities from the gold ore which hitherto where not removed during the smelting process. There are number of ways in which your refining can be done for gold, the

Minerals Free FullText Release Behaviors of Arsenic

Nonferrous metal smelting enterprises produce hundreds of thousands of tons of arsenic sulfide sludge (ASS) each year in China. Most of the ASS are stored at the companies without enough preventive measures. During the storage and natural drying process, arsenic sulfide is easily oxidized, thereby causing secondary pollution and increasing environmental risks.
