Abstract:

Bor is one of Turkey’s most important underground sources. As a result of the bor enrichment process, large amounts of waste are accumulated and this situation is a threat to the environment. Although there is a lot of work on the use of bor waste as additive in some industries such as cement, concrete, rubber, ceramics, there is not enough work on the acquisition of valuable metals found in the content of these waste. Through the recovery of these metals from waste, the amount of waste will be reduced and the contribution to the country’s economy will be made. Bor waste, especially silk-containing waste, has been found to contain significant amounts of lithium, rubidium, sezyum. Lithium is used in battery production with its unique electrochemical activity. Rubidium and sezyum have similar chemical properties and can be used in many industries, such as night vision devices, telecommunications systems, new technical materials and energy. Lithium lepidolite is found in the mineral. Rubidium and sezyum are derived as a side product in lithium production. They are also extracted in a small amount from the salt lake waters. In this study, by adding calcium chloride and sodium chloride to the bor chloride from Kütahya Emet region, bor chloride/calcium chloride/sodium chloride, 1/0.3/0.2 mass ratio at 950 °C at 1 hour. Chemical processing is applied. The mixture is then mixed with water at 0.02 times the rate of liquid mass. The room temperature is fixed. For each metal, more than 85% of extraction was made.
