Floatability of borogypsum with perlastan

The article discusses the problem of accumulation, storage, use and processing of various production waste. Advantages of mining waste use as a source of manufacturing marketable products are emphasized. The study object is selected to be borogypsum containing gypsum and silicon dioxide applicable in different industries. The current processing methods of borogypsum are reviewed. A new flotation agent is proposed to extract silicon concentrate from waste of boric acid production. The mathematical planning methods are used to carry out the multi-factor experiment which reveals the optimal mode of flotation. The selected factors are: the temperature, pH, concentration of the main flotation agent, agitation time, as well as the flotation duration. The data of experimental investigation are presented for initial raw material and produced samples. The investigations were carried out using the modern physicochemical methods (spectrophotometry, IR spectroscopy, scanning electron microscopy, X-ray phase analysis), which made it possible to analyze chemical ad mineralogical compositions, as well as structures of samples. The implemented research shows that perlastan ON-60 is a promising flotation agent for borogypsum.
