Jackman and Sarbutt (1990) found that solution changes during leaching gave a dramatic improvement in gold recovery on a 74-mm gold–tellurium concentrate grading 218 g/t Au, 410 g/t Te and 41.7% S, the major tellurium mineral being montbrayite [Au 2 Te 3]. Gold recovery improved from 92% to 98% with two solution changes.

Carbon, as a media of recovery for gold from leach solutions, did not gain wide acceptance in the gold industry until the 1970's, with the explosion of heap leaching of vast quantities of low grade gold ores, and subsequent production of many gallons of pregnant leach solution.

The melting point of gold is 1063 ˚C, which is a higher temperature than can be obtained by cheap torches and burners. By adding borax to the heavy mineral concentrate, the melting point temperature decreases, allowing people to melt gold out of their concentrate and salvage. By using borax, no mercury flour is produced, and gold recovery

The Merrill–Crowe Process is a separation technique for removing gold from the solution obtained by the cyanide leaching of gold ores. It is an improvement of the MacArthur-Forrest process, where an additional vacuum is managed to remove air in the solution (invention of Crowe), and zinc dust is used instead of zinc shavings (improvement of Merrill).

for the chemical refining of gold from chloride media has shown considerable promise for the selective extraction of gold from silver, platinum-group metals (PGMs), and base metals, and has potential applications in the refining of gold from various feed materials.
