Cement plant sources raw materials from local limestone quarry, andsupplements kiln feed with sand and clay purchased from independentsupplier.

What is the best mix of quarried and imported materials which, whilemeeting the silica and lime modulus targets, also minimizes the cost ofproduction and maximizes the operational life of the quarries and kiln?

What is the optimal extraction sequence in the limestone quarry (theoptimal blended pit)?
