Mineralogical composition of mining wastes deposited in voluminous tailing impoundments around the world is the key factor that controls retention and release of pollutants. Here we report geochemical and mineralogical investigation of one tailing impoundment from Slovakia. Ore deposit RudЕ€any was exploited from the end of 19th century and at 1963 the ore started to be extracted by flotation process (barite, siderite and sulfides). Waste after flotation was deposited into one tailing impoundment, which carries ap...

Geotextiles are used commonly in domestic solid waste disposal sites as a protector filter and separator. Because, sand and silt particles included in waste leachate can fill space of gravels which are using as drainage layers. Therefore, the space of the drainage layer is bunged up with particles and it is decompose. This case is not wanted so the usage of the geotextiles has quite importance in waste disposal sites. In general, geotextile lies between waste and drainage layers and it is used to filtration. In or...

Significant efforts should be devoted to reducing waste outputs from aquaculture operations in order to lower the environmental impacts of aquaculture in many parts of the world. Since most aquaculture wastes are ultimately from dietary origin, reduction of waste outputs should first be through improvements of diet formulation and feeding strategies. The first step in the production of feeds producing less solid waste is to eliminate poorly digestible ingredients (such as whole grain or grain byproducts used as bi...

We propose a device which produces a high density cloud of spray that is consisted mostly of water micro droplets. The cloud automatically occurs when an electromagnetic pulse or/and shock wave from a close explosion matches the device. The ratio of absorbed energy of the dangerous shock wave depends on the density of the cloud and on its spreading speed as well as on the size and the mass of micro droplets. We have developed a mathematical model of physical processes in the Absorber. Numerical simulations show sa...

All materials which are rich in carbon content could be used after activation or adsorption. These materials include coal, lignite, wood, Boone, coconut shells, nut shells, rice husks, and various fruits seeds. Activated carbons obtained from these materials are usually hard and dense. Therefore they could be used in water treatment for long time without deterioration. Activated carbons used in controlling environmental pollution should have high surface area and porosity. Activated carbon is obtained by the proce...

Current management of phosphate-bearing resources (mainly rock phosphates, RPs), which in fact are finite non-renewable sources, is quite far from the principles of sustainability and may cause an escalating price increase mainly because of increases in RP-processing costs. One of the most studied approaches in solubilization of insoluble phosphates is the biological treatment of phosphate-bearing materials. In this work, we propose a microbial extraction of phosphate from insoluble inorganic natural sources as a ...
