The current paradigm argues the Moon formed after a giant impact that produced a deep lunar magma ocean (LMO). After a period of turbulent convection, the LMO experienced fractional crystallization, causing the initially peridotitic liquid to evolve to a plagioclase-saturated ferrobasalt. The lunar crust, much of which comprises 93-98% pure anorthosite [1,2], formed by flotation of positively b...

G. Siwiec, B. Oleksiak, J. Wieczorek Silesian University of Technology, Katowice, Poland A. Blacha-Grzechnik Silesian University of Technology, Gliwice, Poland In the presented study the flotation process has been proposed as a method of enrichment of silver-bearing jewellery waste. This method, traditionally used for the enrichment of non-ferrous metal ores, is based on differences in wettabil...

A methodology for modelling and designing H∞ controllers for an experimental pilot-scale flotation column plant is described. Experimental results, including the modelling procedure and an H∞ design, are presented. For this purpose, different models, for different operating conditions, are determined, by means of system identification techniques. A strategy to get the uncertainty model, using a...

The function(s) of soluble silicates in repulpinghashing and flotation deinking of waste newsprint/magazine were investigated extensively, under optimized conditions. During repulping/washing, silicate ’s response was characteristic of a buffer and a detergent. It was responsible for a 3.0% increase in I S 0 brightness. In repulping/flotation, silicate accounted for a 6.1% increase in I S 0 bri...

Flotation tailings from copper production are deposits of copper and other valuable metals, such as Mo, V and U. New hydrometallurgical technologies are more economical and open up new possibilities for metal recovery. This work presents results of the study on the extraction of copper by mixed extractant consisting p-toluidine dissolved in toluene. The possibility of simultaneous liquid-liquid...

Clinical and histopathological findings in a litter of German Shepherd dogs consisting of seven puppies with acute inflammation confined to the footpads were reported. Affected footpads were characteristically erythematous, swollen and painful. Lesions were present on all four feet in 3/7 cases and on the rear feet in 4/7 cases. None of the dogs had evidence of ectoparasitism. Fecal flotation, ...

The influence of several parameters on removal of various impurities during vacuum flotation clarification of mixed juice has been investigated, and possible ways of dealing with the secondary precipitate obtained in this clarification process have been examined. Dispersed a~ir flotation clarification is described and the experience gained with this separation technique is recorded. Introductio...

A fast method for separation, preconcentration and determination of cadmium in drinking (source, well, tap) and water for irrigation is described. Iron(III) hexamethylenedithiocarbamate, Fe(HMDTC)3, has the role of colloid precipitate flotation collector. The determination of cadmium in final water solutions preconcentrated by flotation can be performed by flame (FAAS) or electrothermal atomic ...

A dispersed-ozone flotation (DOF) separator was devised for a pilot study of tertiary wastewater treatment for re-use purposes. As a compact device combining coagulation, ozonation and flotation in an integrated unit, the DOF separator achieved a very high removal of SS, TOC, UV254 and colour, as well as effective inactivation of coliform and total bacteria within a short hydraulic retention ti...

Exploring new ways to acquire niobium resources is essential resolve supply risks, due the fact that, at present, 99% of controlled by only two countries. In present work, a flotation technique was applied separate from low-grade niobite ore. To maximize utilization original ore resources, pre-flotation conducted recover sulfur and eliminate adverse effects sulfide on flotation. The obtained gr...
