Throughput and product quality control for a grinding mill circuit

Although it is desirable to have independent control of the circuit’s product quality and throughput, these variables are inversely proportional (Bauer and Craig, 2008). A degree of independent control of quality and throughput cannot realistically be achieved without su cient independent manipulated variables. 1.1. Control of grinding millThe process quality management of the gold CIP plant is an important part in the production of gold mines. It includes 7 aspects: raw ore management, crushing process quality management, grinding quality management, leaching adsorption quality management, desorption and electrowinning quality management, smelting quality Process Quality Management of Gold CIP Plant Explained
