The recycling of rare earth elements and base metals from recycling slag powders of nickel metal hydride (NiMH) batteries by ionic liquid leaching was studied. Leaching tests were conducted by using the ionic liquid 1-methylimidazolium hydrogen sulfate (HmimHSO4) selected after some preliminary leaching tests on slag powders. The HmimHSO4 concentra...

Slag properties affect the efficiency of Electro Slag Remelting (ESR) process by removing the quality impairing elements (S, P, etc.), while avoiding valuable alloying element losses. Therefore, a relation between element losses and optical basicity of slags, which may be assumed to be an enhanced approach to basicity concept, would play a crucial...

Slag properties, such as electrical conductivity, thermal conductivity, density, viscosity, and surface tension, and the prediction of these properties play an important role in melting and metal refining. Optical basicity depends on the electronegativity of the ions of an individual oxide. This feature represents the bonding characteristics, ioniz...

The increasing consumption of plastics inevitably results in increasing amounts of waste plastics. Because of their long degradation periods, these wastes negatively affect the natural environment. Numerous studies have been conducted to recycle and eliminate waste plastics. The potential for recycling waste plastics in the iron and steel industry...

Brass ash from the industrial brass manufacturer in Turkey was leached using the solutions of ionic liquid (IL) 1-butyl-3-methyl-imidazolium hydrogen sulfate ([bmim]HSO4) at ambient pressure in the presence of hydrogen peroxide (H2O2) and potassium peroxymonosulfate (oxone) as the oxidants. Parameters affecting leaching efficiency, such as dissolut...

Chromite is an important strategic mineral usually associated with other gangue minerals, mainly silicates. The selective flotation of chromite minerals of any chromite ore have some difficulties due to dissolved cations from gangue minerals. By this work, selective flotation of various chromite ores were studied to determine some of the features o...

Brass production by smelting copper scrap alloys and zinc ingots in electric furnaces is a common pyrometallurgical process. Copper scrap is melted at about 1050 °C and zinc is added in the liquid pool. Wastes like ash and dust occur during that smelting step containing a considerable amount of metallic values. The recovery of these metals via conv...

Using of plastics in the world increases day by day and the amount of waste plastics increase as a result of high consumption. The long degradation period of plastics in nature cause the plastic wastes to be a major problem for environmental damage and pollution. By recycling of plastics these problems can be eliminated. For this aim plastics can b...
