This article provides an in-depth analysis of the factors affecting the selective dissolution of tungsten cakes in sodium carbonate solution - particle size, soda solution concentration, sodium tungstate and bicarbonate content, and bulk density. According to the experimental results, it was found that a decrease in particle size and an increase in soda concentration significantly increase the degree of tungsten dissolution. It was also noted that a change in the molar ratio of Na2WO4 and Na2CO3 in the initial solution has an inversely proportional effect on the dissolution kinetics.
