Selection of lead-zinc flotation circuit design by applying WASPAS method with single-valued neutrosophic set

Abstract

In this paper, selection of adequate circuit design of lead-zinc froth flotation, which has a significant impact on the processing costs and useful minerals utilization, is considered. This complex selection problem can be adequately presented as an MCDM problem. Three different circuit design schemes are considered: Sequential Selective Pn-Zn flotation, Collective-Sequential Selective Pn-Zn flotation, Collective Pn-Zn flotation. An approach for solving complex decision-making problems based on the use of WASPAS method and singlevalued neutrosophic sets, namely WASPAS-SVNS, is proposed. The efficiency and usability of the proposed approach are considered on the example of a lead-zinc flotation scheme selection problem.
