Efficient volume reduction and concentration of mining waste water with direct contact evaporation technology
Enermin 2016 International Seminar on Energy Management in Mining (August 2016)
by Steven Panz and Wesley Young of Inproheat Industries.
Efficient and effective treatment of mining related waste solutions is a global concern. This presentation illustrates the principle fundamentals of direct contact heat transfer, namely Submerged Combustion, and how this energy efficient principle can be applied to the concentration of waste water liquid streams through evaporation.
Submerged Combustion Heating and Evaporation
by Wesley Young and Steven Panz of Inproheat Industries.
Submerged Combustion is a method of direct contact heating that has been practised in a wide range of industries for several decades. This article explains the basic concepts of submerged combustion and how it can be applied to process heating of industrial aqueous solutions and slurries, and to the evaporation of solutions for the purposes of concentration or volume reduction.
Efficient heating of heap leaching solutions to minimize GHG emissions and cost of energy
Infomine Heap Leach 2013 Conference (September 2013)
by Steven E. Panz and Wesley Young of Inproheat Industries.
This presentation focuses on the application of heating an aggressive low pH 1.0 to 2.0 Raffinate Solution at a copper heap leach operation. It discusses the technical design challenges that had to be overcome to utilize submerged combustion as the heating method and the resulting benefits realized.
Heating Iron Ore Slurry to Improve Filtering Efficiency Prior to Pelletizing
CIM Conference (May 2010)
by Robert E Wood and Wesley Young of Inproheat Industries.
This paper describes the design process and expected outcomes of a slurry heating system, using submerged combustion technology, at an integrated steel plant in Mexico. The benefits of heating the slurry prior to filtering has been shown through independent studies, but has not been considered until now because of the high cost of heating the slurry using conventional heating technologies, such as a boiler / heat exchanger system, or direct steam injection.
