The Modified Hallimond Tube Microflotation Cell is a specialized laboratory unit with a total internal volume of approximately 120 mL, designed for microflotation tests using small mineral samples (typically 1 g). It features a bottom part with a frit for air passage, a middle section, and a top part. Similar to the Partridge-Smith cell, it assesses mineral response to specific flotation conditions like pH and reagent dosage, with an air flow rate around 35 cc/min. A key advantage of its bending shape is the minimization of floated particles falling back into the pulp, enhancing separation efficiency for precise studies of mineral hydrophobicity and flotation kinetics.
