The microscale, naturally occurring radiation damage accumulation in biotite mica by α-particles has been studied before. Commonly exhibiting darkened aureoles of α-radiation damage surrounding micrometer-scale radioactive inclusions, biotite is a useful proxy for studying the complex, heterogeneous nature of radiation damage in layered …

Department of Chemical Engineering, Michigan Technological University, Houghton 49931, United States Received 24 July 2020; accepted 20 January 2021 Abstract: In flotation, metal ions possess significant roles that are usually fulfilled by either selectively activating or depressing the target minerals. Despite that tremendous efforts …
The interaction of guar gum with biotite mica has been investigated through adsorption, flotation and electrokinetic measurements. The adsorption densities of guar gum increase with increase of pH and the isotherms exhibit Langmuirian behaviour.

Next. First let's change the amount of the Flotation Depressants used. The valuable mineral that isn't liberated from the unwanted mineral will begin to be depressed along with the waste. For the floatation operator, the change that will become most apparent is, that the color of the froth will begin to reflect more of the wanted mineral ...

Micro-flotation outcomes indicated that the quartz floatability was more than phlogopite and biotite. In the presence of 30 mg/dm 3 EDA, their recoveries were 97.1, 46.3, and 63.8%, respectively.
Selective flotation of muscovite from a material containing muscovite (15.4%), biotite (13%), and siliceous gangue (quartz and feldspar), using a mixed collector system of sodium oleate and dodecylamine acetate has been described. Muscovite is found to float in preference to biotite, when the pulp is initially conditioned with oleate followed …
The flotation recovery obtained for phlogopite, biotite and apatite in the microflotation tests as a function of collector concentration and pH are presented in Fig. 4, Fig. 5, respectively. Great selectivity was observed with low POC concentration (2 mg.L -1 ) and could even be enhanced at higher concentrations with no detrimental effects on ...

The quartz ore used in this experiment is from Hanzhong City, Shaanxi Province, China. The quartz sample was ground by a ball mill, and the part with a particle size of -212+109 (mu) m was selected for the flotation experiment. For ICP and XRD tests, the samples were further ground to -20 (mu) m. The impurity compositions in the …
