Hydrometallurgy
Pressure Leaching / Oxidation

SNC-Lavalin is a global leader in pressure leaching technologies, including all aspects of autoclave design and applications.  Installations include several gold facilities in Nevada as well as facilities for nickel in Australia and New Caledonia. 
 
Heap Leaching
We have completed various heap leaching projects for both gold and copper recovery in both North and South America.   
Solvent Extraction  We have a proven track record in the application of solvent extraction for the recovery of copper, uranium, nickel, magnesium, vanadium and rare earth elements.

Pyrometallurgy
We maintain a leading position in the study, design and construction of pyrometallurgical plants throughout the world. Our smelter expertise is internationally recognized and is enhanced by a sound reputation in the design and modernization of associated gas collection facilities.

Electrorefining / Electrowinning 
We have provided extensive consulting services for the development of these facilities, including full participation in the design, construction and operation of electrolytic refining plants in many parts of the world.

Projects Contacts

Cortez Hills Gold Project

In August 2006, SNC-Lavalin was awarded the EPCM contract for the Cortez Hills Gold Heap Leach Project.  The materials handling system consists of a belt conveyor system in multiple flites that is to traverse a distance of approximately 15 kilometres.  The capacity of the system will be 1,000 tonne/hr.  The terrain is not particularly challenging however the route will be integrated into an existing facility.  Services: EPCM

Country : United States

El Pachon Copper Project

SNC-Lavalin was awarded the contract for a Pre-Feasibility Study for the El Pachon Copper Mine in Argentina.  The Project consists of an open pit copper mine, a processing plant, and a tailings storage facility to be located in Argentina, and a concentrate pipeline, filtration plant and port facility to be located in Chile.  The Project is based on a plant capacity of 1,000 tpd.Services:  Pre-Feasibility

Country : Argentina

Goldstrike Gold Project

We have been involved with the Goldstrike Mine since its inception in 1988.  For each of the five phases of development, we have provided engineering, procurement and construction management services.Services: EPCM

Country : United States

Goro Nickel Project

After providing detailed feasibility studies and EPCM services for the integrated pilot plant of the major nickel project, we are now providing services related to the EPCM execution of the Project for a greenfield nickel mining and processing complex to recover nickel and cobalt from the Goro nickel laterite deposits of southern New Caledonia.  We provided engineering design to the execution of the project as part of the integrated owner's team and the services included site support facilities, port, bulk storage, utilities, industrial and social infrastructure.  Extensive use of modularization and low cost engineering centres has reduced the manpower on site and leveraged lower labour rates.Services: EPCM
