Innovation and Experience

Sherritt Technologies’ success in commercializing projects for Sherritt’s core businesses and external clients is owed to its practical applications of complex technology. The disciplined application of Sherritt’s expertise instills a tremendous level of confidence in clients.

Sherritt Technologies’ research teams are focused on providing innovative process development that has the potential to transform the metallurgical processing and mining and other industries.

Current initiatives include:

  • Bitumen upgrading
  • Artificial Intelligence for autoclave supervisory control
  • Next generation laterite technologies
  • Vanadium pressure oxidation
  • Copper recovery processes from arsenic bearing ores and concentrates

Bitumen Upgrading

Sherritt’s Technologies’ innovative process to upgrade bitumen utilizes its proprietary hydrometallurgical processes and autoclaves, and systems to potentially revolutionize the transport of heavy oil. When fully developed, Sherritt’s bitumen upgrade process has the potential to save millions of dollars in diluent each year and significantly increase the efficiency of oil transport.

Sherritt’s process is based on the use of reactor technology that involves combining hydrogen with bitumen under pressure at high temperature in the presence of a proprietary catalyst suspended through mechanical agitation to eliminate the need for addition of diluent, a high-cost thinning agent that reduces heavy oil viscosity, and improve pipeline capacity.

The process has been proven successful in pilot plant testing. Currently Sherritt is progressing the design of a demonstration plant.

Non Ferrous and Precious Metals

More than 40 commercial operations on six continents successfully employed Sherritt technology for the recovery of non-ferrous (nickel, copper, cobalt, zinc, uranium and others) and precious (gold, silver and platinum group metals) metals. Sherritt has provided technologies and expert services to most of the world’s major mining companies.

Refractory Gold

Sherritt’s process for treatment of refractory gold feed materials provides significantly increased gold recoveries while producing environmentally stable residues (particularly those with high arsenic), and is compatible with conventional cyanidation and other gold recovery processes. Learn more

Zinc Concentrates

Sherritt’s Zinc Pressure Leach technology allows for production of zinc and elemental sulphur from sulphide concentrates, alone or in combination with other feeds, without the simultaneous production of sulphur dioxide or sulphuric acid. Learn more

Copper Ores and Concentrates

Sherritt has conducted numerous research programs, from laboratory to pilot plant scale, to develop economically competitive and environmentally acceptable pressure leach technology for the treatment of copper-iron sulphide ores and concentrates. The major benefits include high recoveries of both copper and precious metals, and conversion of sulphur to the elemental state, or alternatively its fixation as gypsum or sulphuric acid for oxide ore leaching. These hydrometallurgical process may also be readily integrated with existing smelting operations to process selected copper concentrates, roaster dusts and other copper bearing feedstocks. The copper pressure leach processes can be adapted to the treatment of arsenic-bearing feeds for the recovery of copper and gold with fixation of arsenic as a ferric arsenate (or scorodite) residue.

Metal-Bearing Sulphides

Sherritt has developed technologies to recover non-ferrous and precious metals from sulphide concentrates and other feed materials which are not economically suitable for treatment in conventional smelters. These technologies offer high recoveries of the metal values while producing an environmentally stable residue.

Mattes

Sherritt has developed and commercialized technologies to recover nickel, cobalt, copper and platinum-group metals from mattes and other feed materials.

Nickel Laterites

Sherritt’s technologies to recover nickel and cobalt from laterite ores have been applied in Sherritt’s own operations for more than 50 years and today are accepted as the preferred processes for treatment of laterite feeds amongst commercial plants.
