| description | Research on kinetics of change of phosphorus, niobium, vanadium and titanium content during high-temperature roasting of ore from Tomtor field mixed with active additives: bicarbonate (NaHCO3), sodium carbonate (Na2CO3), alkalis (КОН, NaOH) is conducted. An equation of ore roasting kinetics is proposed and values of constant rate of high-temperature ore roasting for phosphorus, niobium, vanadium and the titanium under various conditions are calculated. Relationships of constant rate of high-temperature ore roasting in the atmosphere of air oxygen, argon and molecular chlorine to the temperature of roasting and content of active additives are obtained. It is established that in the atmosphere of air oxygen, ore roasting is most effective with additions of NaHCO3, Na2CO3, NaOH, taken with the ratio (1:1). It is shown that roasting of ore in admixture with carbonates and alkalis can translate into a solution for subsequent leaching at minimum 95.0% of phosphorus and 44.0% of vanadium contained in the original ore. It is established that the greatest rate of roasting in the atmosphere of oxygen is characterized by ore roasting in a mixture of NaHCO3 and NaOH. The constant rates of that process for phosphorus and vanadium are calculated. It is established that filter cake forming after ore roasting requires further processing because it contains high concentrations of vanadium and other valuable metals. |
