InLine Spinner

Gold recovery unit that separates coarse and fine particles

  • Proven performance efficiency
  • Consumes a very small volume of water
  • Extremely effective for recovering coarse free gold from concentrates

Clean, high-grade concentrates of gold and heavy minerals are achieved with Gekko’s InLine Spinner (ISP). The simple, low maintenace ISP is a cost-effective tool for separating coarse and fine particles. 

Adding an ISP to mine operations will upgrade recoveries from intermediate or low-grade ores and lower operating costs. It requires no water for elutriation, is fully automated and can produce a high-grade smelter-ready product. Furthermore, because the product volume is smaller, fewer chemicals are required downstream, offering significant cost savings. 

Another Step Forward in Gravity Seperation

Often incorporated as a second gravity step for mining operations, the ISP further concentrates and upgrades material from the IPJ or other jigs.

This simple unit for small applications contributes to the overall success of a process flowsheet and offers a cost-effective way to separate free gold from sulphides. The ISP is extremely effective for recovering coarse free gold from concentrates and for alluvial operations.

Low water consumption by the ISP reduces the total water required in plant operations. Furthermore, the ISP’s fast dump cycle saves time and speeds up processing.

In addition, higher recoveries of coarse and fine particles lower mine operating costs substantially. A fully programmable logic controller automates ISP operations to improve workflows and reduce down time.

How the ISP works

A pre-concentrated slurry is fed into the ISP’s spinning polyurethane bowl. The bowl spins with low centrifugal force to create a vortex in the slurry. This action forces the dense mineral-containing particles to gently sediment against the inside wall of the bowl in small ridges or ‘riffles’.

Simultaneously, a swirling metal bar, called the cutter bar, circles the inner face of the bowl, parallel to the mineral deposits, creating a mechanical turbulence like a river eddy. This releases light gangue particles trapped underneath that are contaminating the dense mineral particles.

Other batch centrifugal concentrators perform this function using water spray units that require distilled water on site and continuously supplied to the unit, complicating the instrument.

In addition, other concentrators use higher g-forces to speed up the process, however this can promote contamination and other problems associated with compaction of material.

The depth and design of the riffles is important and provides a clean separation zone to heavy mineral particles with extremely low gangue contamination.

Light tailings spill over the top of the bowl and are removed via the tailings outlet. When the batch spin is complete and the waste products have been removed, high pressure water jets flush out the riffles in a small volume. The concentrate is collected from the outlet at the bottom of the bowl. 

 

Innovation

The innovative ISP design, based on well-established metallurgical concepts, is a low risk, low cost, high performance unit.

Low Water Use

The ISP consumes a very small volume of water, compared to other centrifugal systems, in order to flush the bowl.

Improved Recoveries

The ISP consumes a very small volume of water, compared to other centrifugal systems, in order to flush the bowl.

Accelerated Cash Flow

Lower operating costs, and therefore faster financial returns, are achieved due to the ISP’s simple design and minimal water requirements.

Flexibility 

The ISP’s rapid concentrate dump cycle allows operators to vary machine parameters in step with the processing run to achieve higher-grade recoveries.

Fast Delivery / High Availability 

The simple ISP design makes it straightforward to manufacture, which ensures a fast lead time, but also provides easier maintenance, thus reducing downtime.
