Sommaire: This paper describes the operations of the open pit and emphasizes particular aspects of Les Mines Selbaie. The open pit as well as its related services were incorporated into a complex which includes an underground mine and a concentrator. The equipment was chosen with the objective of auto-sufficiency during each phase of mining. The paper outlines the organization and the methods used in each step of mining, notably: drilling, blasting, loading, transporting and crushing. The responsibilit...

Sommaire: Selbaie is located northwest of Joutel, in what is known as the fourth east-west volcanic sediment group in northwestern Quebec. The main metals produced are copper and zinc, with important contents of both silver and gold. Production comes from an open pit mine on the A-l zone and from two underground mines on the B zone and the A-2 zone. Each mine gave rise to important capital investment programs for construction and mine development, all of which were managed and staffed with company-hire...

Sommaire: Mineral exploration for PGE (PGE: platinum, palladium, iridium, osmium, ruthenium, rhodium) requires appropriate measurement methods. Selecting an appropriate analytical method must take into account several factors. The most important ones are: the type of material to be analyzed, its representativity, the required detection limits and the operational cost. Several analytical approaches are possible, all of which require a preconcentration step. One of the most appropriate methods consists...
