The DENVER Lab Cell D-1 is a versatile bench-scale flotation machine designed for laboratory-scale mineral flotation studies. It can be configured with three different cell capacities: 500 mL, 2.5 L, and 5 L, allowing researchers to test various sample sizes and optimize flotation parameters. This machine is typically used to separate valuable minerals from gangue minerals, or vice versa, based on their surface properties. It's a fundamental tool for investigating and optimizing processes such as reagent dosage, pH, and air flow rate in mineral processing research, and is widely applied in metallurgical and mineral separation studies.
