To implement data calculating, relative matrix is used to express the flotation flowsheet, special mineral processing models and optimizing mathematical models have been used. The “binary tree” principle has been used to demonstrate the flotation flowsheet structure, and the coding principle according to the order of preorder traversing to “binary tree” is determined for the implement of the flotation flowsheet drawing. As a result, the computerization of flotation technology design was completed. Design principles, models and application of the software are discussed in this paper.展开更多
