Keene Mini Max Power Sluice Concentrator Kit – 12V Portable Gold Recovery System

The Keene Mini Max Power Sluice Concentrator Kit is a versatile, portable gold-recovery system designed for prospecting, bulk sampling and final concentrate cleanup. Its adaptable design allows it to function as a power sluice, fine-gold concentrator or conventional stream sluice.

The updated Mini Max uses a single high-output 2,200 GPH 12-volt pump, an 8-foot pressure hose and a ball valve for precise water-flow adjustment. Material passes through the upper hopper and removable classifier screen before reaching Keene’s green rubber riffle mat in the lower sluice, where fine gold and other heavy material are captured.

For concentrate cleanup, replace the green rubber riffle with the included Miracle Matting and install the finer woven hopper screen. The removable upper sluice also makes it easy to inspect the lower recovery area without performing a complete cleanup.

Three Ways to Use the Mini Max

• Power sluice: Process bank-run material using the included 12-volt pump

• Concentrator: Install the finer screen and Miracle Matting for controlled concentrate cleanup

• Hand sluice: Attach the included flare for use in a suitable natural stream

A suitable 12-volt power source and water supply are required for powered operation. Always classify material appropriately, adjust water flow gradually and save initial tailings until recovery performance has been confirmed.

The new and improved Mini Max Power Sluice Concentrator is the multi-tool of prospecting. We have changed our updated machine from a double pump system to one single, larger pump. The new pump provides not only greater water flow and higher head lift but also a larger diameter pressure hose which creates a higher flow than the double pump system. We've also doubled the hose length to 8 feet, added a new ball valve for precise flow control and a screw on connector that requires no tools.

Whether you are working river banks, desert placer's or just cleaning concentrates for larger dredges and equipment, the Mini Max is a prospecting tool that will always be part of your arsenal. This multi purpose package includes a removable mat for the lower sluice box, converting it to a professional clean up machine simply by sliding out the green rubber riffle and replacing it with Miracle Matting. It is also supplied with an additional finer woven mesh screen on the top hopper for using it as a concentrating system. Another new improvement is that the Mini Max is powered by a single 2200 GPH, 12 volt pump made proudly in the U.S.A. The top hopper is equipped with a flood header that provides smooth water flow through the trough, over a slick plate and in to a 6 inch section of miracle mat that gives you a preview to any captured gold! The top sluice lifts off easily so you can inspect the lower sluice, eliminating the need for cleaning. The material is then washed over a removable classifier grizzly screen, removing the oversized waste gravel. The bottom sluice box is lined with our green rubber riffle that recovers ultra fine gold and can handle larger volumes of material. When used as a concentrating system, the lower sluice is partially covered by oversized expanded metal. When used as a power sluice you can expect a capacity of up to a quarter of a yard per hour and about a third of its capacity when used as a concentrating machine. This Mini Max can also be operated by a small, single gas powered pump such as our P90G Pump Kit. This device is ideal for back packing given it folds up into an compact size of 36 by 14 by 7 inches and weighs under 23 pounds. The four independent legs fold up with our new pin-lock folding system with large wing nuts that make it a breeze to adjust elevation and articulation. The Mini Max also includes a mountable flare for use as a hand sluice.
