Abstract
Optimizing design of the problems in open-pit mining and metallurgy projects not only helps to reduce production costs and increase economic benefits, but also can save resources and protect the environment. By analyzing two examples in mining and metallurgy, this paper shows that operations research can provide scientific decision-making tools and methods for mining and product quality control. Question 1 on the premise of the best overall benefit, arrange ore production at each mine site. This is a 0-1 planning problem, combined with linear programming problem-solving ideas, the establishment of mathematical models, using lingo software solution, come to the best mining program. Problem 2 through the establishment of a mathematical model of linear programming, has been to meet the product quality requirements, and the lowest cost processing program.
