A simple, yet powerfull tool for plotting cumulative percent oversize against particle size while using combination of a logarithmicand double logarithmic axis (RR diagram) is here proposed. It has direct support for line approximation and thus RRdis

Magnesite ore with a low chalcopyrite – cobaltite mineralization was subjected to a series of separations designed to evaluate thepossible concentration of the two accessory minerals. Although the Cu-Co grade in the ore (> 0.01% Co, > 0.1% Cu) is s

Using the separation methods, the tetrahedrite concentrate, which contains multiple elements, was obtained from the tetrahedrite ore.We focused mainly on copper, but also on iron and antimony. Ore also contains undesirable elements such as arsenic or

The cationic gemini surfactant 1,4-bis(dodecyl-N,N-dimethylammoniumbromide)butane (BDDAB) was tested as a possible collector in the reverse froth flotation of magnesite ore. This novel type of collector was compared with its conventional monomeric eq

This work describes improvement of mechanical properties of alkali activated binders – geopolymers made of fly ash from coal combustion in fusion boiler. The effect of addition of amorphous phase on physico-mechanical properties of geopolymers was

There is a long-lasting uncertainty as to the structure of the metal oxide/water interface. Various structures have especially been invoked to rationalize the seemingly anomalous silica/water interface. But, none of them seems to be approved in a qua

The motivation for this study was the increasing need of recycling waste plastics in the cleanest - separated form. Relatively inexpensive methods of physicochemical separation of plastics is based on the different wettability of their surfaces. Beca

We introduce a new method of evaluating the structure of electric double layer (EDL) at the native solid/liquid interface using cryogenic X-ray photoelectron spectroscopy technique. This method is based on evaluating the atomic concentration ratio of
