Polymetallic compounds contain a combination of different metals.

It is possible to recover and separate multiple metals from a single polymetallic ore deposit. For instance, lead, silver and zinc frequently exist in the same ore and have high, yet differing, specific gravities.

Traditionally, polymetallic compounds were separated by flotation or dense media separation processes.  However, the development of continuous gravity devices, such as Gekko’s InLine Pressure Jig, employs gravity separation to recover metal compounds from polymetallic ores in a cost-effective manner.

Gravity separation is used to effectively process polymetallic compounds

Polymetallics Recovery

Gekko’s innovative InLine Pressure Jig is the core technology for recovering multiple metals from polymetallic material. The IPJ utilises the differences in specific gravity of different metal-bearing minerals. This allows improved separation of each metal for easier, more cost-effective downstream processing.

In addition, Gekko’s world-class technical specialists in gravity separation techniques are the key to developing a viable flowsheet for, and profitable returns from, this type of ore deposit.

Gekko's Approach

Gekko recommend complete laboratory testwork on all polymetallic ore deposits. This will ensure that Gekko metallurgists and engineers understand the material’s metal composition and important gravity separation considerations.

Gekko will recommend and design an optimal recovery flowsheet for polymetallic deposits that also achieve low operating costs, low capital expenses and have a low environmental impact.
