This study presented the first in a series of investigations currently underway to develop efficacious, cost-effective, and benign processing opportunities produce rare earth elements (REE)–rich concentrate from an Australian complex low–grade saprolite ore [1.14% total oxides (TREO) grade], which is primarily exploited for its gold copper values. work specifically preliminary flotation investi...

This paper describes the results of a beneficiation study conducted on low-grade fluorite ore. The was aimed at development suitable process to produce chemical grade concentrate. representative sample ore up-graded by leaching and flotation process. important parameters froth were optimized obtain highest recovery A single-factor variation method applied get optimum conditions rougher concentr...

Recycling is a potential solution to narrow the gap between supply and demand of raw materials for lithium-ion batteries (LIBs). However, efficient separation active components their recovery from battery waste remains challenge. This paper evaluates influence three routes liberation LIB (namely mechanical, thermomechanical, electrohydraulic fragmentation) on lithium metal oxides (LMOs) spheroi...

The United Nations’ Sustainable Development Goals have sparked growing interest in biosurfactants from many surfactant-loaded industries including those utilizing froth flotation for mineral separation. However, the interaction of with surfaces is currently poorly understood. We bridge this gap by studying adsorption a yeast-derived bola acidic sophorolipid (ASL) biosurfactant on djurleite (Cu1...

Increasing demand for lithium-ion batteries has led to the development of several new lithium mineral projects around globe. Some major processing challenges these face are similarities in gangue and value behaviour poor selectivity froth flotation. Unsaturated anionic fatty acids primary spodumene flotation collectors, known be strong collectors with solubility selectivity. Fundamental researc...

It is challenging to measure the hydrodynamics of stirred tank reactors when they contain multiphase flows comprising liquid, gas bubbles and particles. Radioactive particle tracking techniques such as positron emission (PEPT) are only established determine internal flow behaviour due inherent opacity density fluid vessel walls. The profiles solids an important tool for robust reactor design op...

This study is focused on the froth flotation reprocessing of a copper mineral from tailings. The effects parameters including pulp density, collector dosage, frother and dispersant dosage were statistically examined to obtain an effective approach for concentrating minerals. sample ore used in this was mainly wastes that have been stored more than 30 years comprised mixed sulfide minerals parti...
