A method for production of potassium antimony tartrate by utilizing one or more residues bearing antimony includes the step of leaching of the one or more residues bearing antimony for a first pre-determined time interval in each of one or more jacketed reactors. In addition, the method includes filtering obtained slurry from a leached solution of the one or more residues products bearing antimony to obtain an aqueous solution and a solid residue. The method also includes crystallizing the obtained aqueous solution to form one or more crystals of the potassium antimony tartrate in a jacketed crystallizer. The antimony contained in the one or more residues is in an oxidic form and the oxidic form of the antimony is more than 20%. The solid residue is a leached cake.
