BACKGROUND Cavitation is a rather common and important effect in the processes of destruction of nano- and microscale particles in natural and technological processes. A possible cavitation disintegration of polymineral nano- and microparticles, which are placed into a liquid, as a result of the interaction of the particles with collapsed cavitation bubbles is considered. The emphasis is put on...

A heavy media column is used for the separation of the mineral fractions of a sample. Thus the directly weighed per cent of the mineral composition of the rock or ore sample is accomplished. ttre teihnique may be applied to the concentration of a particular species, e,ren i.r trace amounts, for further mineralogical studies or for practical commercial metallurgical mineral beneficiation purposes'

Clay from deposit Bilalovac, Central Bosnia, was characterized by chemical, IR, XRD and DTA/TG analysis. The major mineral components are kaolinite, illite, muscovite and quartz. Raw clay may be used for pottery products and terracotta. Clay was beneficiated by wet method removing fraction over 20 μm. Beneficiation process increased content of kaolinite and decreased content of quartz. Benefici...

This paper with the title Waste Management in Mining Industry mainly deals with the large amount of waste generated by the mining industry in the process of extraction of minerals which is a great threat to the environment leading to air pollution soil pollution and many other hazardous effects to the environment as well as human lives . This paper broadly discusses about the different type of ...

Reaction of N-phenyl-pivalohydroxamic acid with Ce(III) precursors leads to a homoleptic hydroxamate complex: Ce(IV)[(t)BuC(O)N(O)Ph]4. Electrochemical experiments indicate a significant stabilization of the Ce(IV) cation at Ep,c = -1.20 V versus SCE in the hydroxamate ligand framework. The spontaneous oxidation of Ce(III) in a hydroxamate ligand field is discussed in the context of beneficiati...

In the paper are reported results of first stage tests performed to verify possibility beneficiation a wollastonite mineral (calcium metasilicate, CaSiO3). The studied ore comes from mineralized body located in southern part Sardinia (Italy), area named "Gutturu Is Abis". is composed associated with limestone, garnets and silica. approach problem has consisted grinding followed by flotation sep...

The beneficiation process contains a number of links which are closely related to all aspects of the quality of products in a process which has a direct impact on the next one, thus influencing the product quality of all processes. Grinding operations form a critical stage in the middle position of the beneficiation process and is the most important part. Grinding operations here refers to ore ...
