A Gekko flowsheet will recover free gold from different ore sizes with diverse mineralogy and gold distribution.
Free gold is that which can be easily liberated and is unbound to other minerals. Free gold can be rapidly recovered in high amounts using gravity concentration methods.
Traditionally, simply exploiting the high specific gravity of free gold for recovery required little energy and was profit-generating.
Today, however, more milling energy is consumed due to the change in mineralogy of gold resources. For substantial energy savings and proven high returns, an innovative gravity pre-concentration circuit for free gold recovery is essential.
