ORO Concentrators

ORO-Concentrators

The Reverse Multi-Helix Spiral Concentrator is available in 3 models: the 24 "Rougher, the 16 "Cleaner, and the 16 "Finisher. Each concentrator can be set up as a continuous or batch feed. All units are commercial duty, gravity concentrators for both alluvial and fine milled hard rock ores.

Oro's Helix Sprial concentrators can achieve the highest concentration ratio AND recovery possible with any type of ore that can be concentrated by gravity. The design and engineering principles of the multi-helix spirals inside the concentrator allow for full adjustment to the ore-matrix or concentrate, yielding the peak concentration ratio with virtually no loss of gold. With this unique ability, it means higher production rates, and a reduced amount of concentrate resulting in a smelting grade concentrate or finished clean gold.

The Helix Spiral can be setup in parallel, series, or as a stand-alone concentrator; in parallel for higher production rates, in series for mixed materials, and stand-alone for pure gold recovery. The configurations are unlimited. Moreover, by using a 24 "Rougher to feed a 16" Cleaner, and the cleaner feeding a 16" sellable or smelt-grade gold in your hand, without anyone touching it.

Two models:
16” Cleaner 1-2 ton / hour
16” Finisher - up to 1 ton / hour

Cleaner Model Spiral Concentrator

A continuous or batch feed secondary concentrator for processing primary sluice concentrate, primary jig concentrate, centrifuge concentrate, and milled hard-rock ores. Set up as a cleaner, the 16 "or 24 "spiral concentrator is perfect for the application of mercury recovery and tailings projects. For highest production performance, it is recommended to classify material to 1/4 " minus.

Finisher Model Spiral Concentrator

The finisher model can be used in conjunction with our standard Secondary Cleaner to shorten clean-up time when concentrating large volumes, or in certain custom applications. Highest production performance is with fine concentrates of materials less than 1/8 ".Up to 90% of all concentration and clean-up needs can be achieved with the standard 16 "Secondary cleaner. Ask us for advice about your particular application.
