Solution / Elution Heaters for the Heap Leaching Process In Precious Metals Mining CODELCO Mine7.jpgS-1 Gas Solution Heater
  • Strip your carbon column up to five times faster
  • The rugged, reliable design provides an instant, continuous supply of hot solution which increases stripping speed, therefore lowering overhead and increasing profit.
  • Units come fully equipped with controls and instrumentation.
  • Choose from LP gas, Natural gas, and Oil-fired models.
  •  Heater ratings are 1,000,000 to 3,000,000 BTU/hour.
  • All-welded 14-gauge steel frame and 100% stainless steel wetted parts
  • Easy to operate and will last for many years with little maintenance. 


Units are modular so you can make a minimal investment to start, and expand your system as your operation grows. Just install the solution heater, also known as elution heaters, to the required utilities and you are ready to operate the unit. For over 30 years, these units have been operated in North America and many other areas worldwide.




HWP Series: Self-Contained Solution Heating Systems

The HWP Series is ideal for remote locations and combines the rugged Sioux Solution Heater/ Pumping System with a 1,000 gallon atmospherically-vented tank. The unit has multiple pumps: one for each million BTU section to circulate solution through the heater, and one to discharge solution. Tank includes liquid level sensor with water solenoid valve, liquid level sight gauge, adjustable tank temperature control with immersion well, thermometer, ladder, inspection port, and motorized damper. The entire system is skid mounted for portability.

Fuel Fired and All- Electric Hot Water Pressure Washers Are Ideal For Mining Applications

Sioux Corporation is the world-wide leader in manufacturing a full line of application-specific fuel fired and all-electric pressure washers, steam cleaners and combination units that are ideal for use in mining operations. For thirty years Sioux has been the leader in providing high-pressure cleaners to this industry, which can be easily and safely used in underground and open Sioux-Dakota-Series-II.pngpit mines to clean dirt, oil, grease and grime off:

• mining drills

  • Sioux’s line of all-electric steam cleaners and pressure washers heat the cleaning water with electricity, rather than from oil-fired or gas-fired burners. These machines use no fossil fuels and produce no flame or exhaust.
  • Heaters are fully-rated to the stated water flow, so storage tanks are not required, and water temperature is available instantly, and for unlimited time periods.
  • No water preheating or recovery time is needed.
  • Explosion-proof models are designed for hazardous locations. These washers are ideal for underground or indoor use, where air quality is a primary concern.
  • Skid, portable or trailer mounted units available.
  • Sioux offers over 45 models of all-electric steam cleaners, pressure washers and combination units with ratings of 0.6 – 5.75 GPM (2.27 - 21.76 LPM) and 100 – 3000 PSI (6.9 - 206.85 BAR).
  • All-electric pressure washers and steam cleaners are third party certified to UL-1776 and CSA C-22.2 No. 68-92. Explosion-proof models are additionally certified to UL-1203 and CSA 22.2 No. 30-92.Any All-electric unit can be built to explosion-proof standards to meet Class I, Division 1 & 2 specifications. Please consult factory if CE, ATEX, or other international markings/certifications are required.
  • Alternate electricals are available for 50 Hz and any voltage used worldwide.

Since 1939, Sioux has been an industry leader in building application-specific equipment for the most challenging cleaning problems.

SF-20 steam flo steam generatorSteam-Flo® Steam Generators

A source of low pressure steam for a variety of applications. The steam can be used to thaw aggregate, frozen vents, pipes, valves, and controls. The Steam-Flo® can be used to sterilized and sanitize equipment at mine sites to prevent any unwanted cross contamination.
  • Steam-Flo® provides up to 15 PSI (1.03 BAR) steam, and does not require a licensed operator in most areas, reducing insurance costs compared with high pressure boilers.   
  • Utility requirements - 15 Amp service on 115 Volt (60 Hertz) or 220 Volt (50 Hertz), standard garden hose for water supply, diesel fuel, LP gas, or natural gas fuel source.
