Využití odpadů v produkci pigmentů

Abstract

The work deals with the possibilities of use of the waste arising out of pigment production. The theoretical part describes Cu, Fe and pigments in general. It specifies in detail the pigments containing iron and copper and focuses on selected types of metallurgical waste from the Polish steelworks Głogów. The annual metallurgical production in Poland brings about 30 million tonnes of copper ore. This means about 500 thousand tonnes of pure cooper and the rest is waste. The waste can be divided in three groups – mining waste, tailings and metallurgical waste. Metallurgical waste is the subject matter of my work. It is a colourful, solid, dry and hard waste insoluble in water. Mining waste and tailings are rougher and do not differ in colour. Metallurgical waste can be used in many ways, e.g. as gravel, abrasive material, pigments. The experimental part of the work focuses on selected types of metallurgical waste and examination of their use as pigments. Three types of waste with different Cu and Fe content were chosen due to their colours and made into four samples. Based on the relation between the colour and the texture two different samples of one waste were prepared. The use of these types of waste as mineral pigments in lime plasters was studied and they were compared with the industrial pigments generally available on the market.
