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...

The present investigation deals with the recovery of iron values from the screw classifier overflow slimes from an iron ore washing plant by means of reverse cationic flotation as an alternate to direct anionic flotation. Selectivity index, an indicator of separation efficiency, was chosen as the response parameter for optimizing the quantity and evaluating a series of generically same but chem...

The removal of cadmium and turbidity from contaminated soil-washing water was studied by Electroflotation (EF) at the laboratory scale by using sodium lauryl sulfate (SLS) as an anionic surfactant, and calcium hydroxide (Ca(OH)2) as a coagulant. The stoichiometric cadmium to collector (SLS) and coagulant (Ca(OH)2) ratio was 1:4.5. Significant removal of cadmium (100 %, not detected in the resid...

In the present study, microflotation experiments were performed on pure minerals systems involving hematite and quartz in presence of etherdiamine as collector. The influence polyacrylamides co-depressant was investigated a blend with starch depressant. results obtained demonstrated that all used efficient depression, at different levels following order effectiveness: cationic > non-ionic anion...

Starch, dextrin, sodium silicate (SS), and recently co-silicate (SCS) are the most known depressants for depression of iron oxides through traditional reverse flotation. However, all these depressants’ adsorption mechanisms on surface their main associated minerals (silicate phosphates) anionic flotation did not yet been thoroughly investigated. For filling this gap, as a comparative investigat...

Dynamic control of chemical microenvironments is essential for continued development in numerous fields of life sciences. Such control could be achieved with active chemical circuits for delivery of ions and biomolecules. As the basis for such circuitry, we report a solid-state ion bipolar junction transistor (IBJT) based on conducting polymers and thin films of anion- and cation-selective memb...
