An alternative interface for flow injection-capillary electrophoresis based on electrokinetic injection is described. The interface basically consists of tubular platinum and a commercially available standard tee connector. The tubular platinum works as not only an electrode, but also a waste outlet of a split sample solution. The availability of the proposed interface is evaluated by the separ...

As waste management regulations become more stringent, yet demand for resources continues to increase, there is a pressing need for innovative management techniques and more sophisticated supporting analysis techniques. Sequential extraction (SE) analysis, a technique previously applied to soils and sediments, offers the potential to gain a better understanding of the composition of solid waste...

The effect of iron oxide content on the crystallisation of a diopside glass–ceramic glaze was investigated using a glass–ceramic frit in the K2O–ZnO–MgO–CaO–Al2O3–SiO2 system and a granite waste glass. Measurements by X-ray diffraction (XRD) combined with scanning electron microscopy (SEM) and EDX microanalysis showed that the distribution of Fe ions among different crystalline phases such as f...

This study reviews waste water characterization of iron and steel industry and treatment procedures involved in these industries. The production of iron from its ores involves powerful reduction reaction in blast furnaces. Cooling waters are inevitably contaminated with products especially ammonia and cyanide. Production of coke from coal in coking plants also requires water cooling and the use...

At the present day in Russia the change of ferrous metals production technology results in the change of the chemical composition of solid waste from iron and steel works. Traditional approaches to waste recycling methods stop meeting the requirements of geoecological safety. The paper offers a methodology of usage of the ferrous industry waste taking into consideration a life cycle of the mate...

Wind power is growing fast all over the world, and in Sweden alone thousands of turbines has been installed the last few decades. Although the number of decommissioned turbines so far is very low, the rapid installation rate indicates that a similar rapid decommissioning rate is to be expected shortly. If the waste material from these turbines is not handled sustainably the whole concept of win...

In this study we compared three methods for the treatment of electroplating sludge highly loaded with zinc and iron: (1) calcium oxide-based solidification/stabilisation; (2) conversion into inert material by adsorption of organic and inorganic pollutants onto activated carbon; and (3) conversion of mobile waste components into insoluble phosphates. All three methods proved highly efficient in ...

Today, with the advancement of technology, turning waste into fuel has been considered as an inexhaustible source of energy production, especially in industries with high energy consumption. The most important of these industries are Cement and Iron Smelting factories. Babol, as one of the largest provinces in the north of the country, has been facing waste management crisis for several years w...

Estimation of ore reserves is one of the most critical aspects of mining geology. The accurate assessment of the tonnage and grade of run of mine may be the difference between a healthy profitable operation and an expensive early mine closure. The first step in ore reserve estimation is to determine the boundary of ore body or ore/waste contacts. This paper presents a specific mining applicatio...

This paper focuses on research concerning the ecotoxicological properties of granulated slag from the pilot production of gray iron with red mud addition and concrete composites with the application of this slag. Red mud is a hazardous waste generated in the production of aluminium oxide. Negative ecotoxicological tests are, therefore, one of the basic prerequisites for the ability to use granu...
