    The performance of the oxidized coal in a mechanical and column flotation cell are compared in Table 3 and presented in Fig. 10. The minimum ash in the concentrate recovered without cleaning from mechanical flotation is 13.2% with a yield of 8.2%. The single-stage cleaning of the rougher concentrate reduces the ash to 13% with 38.7% yield.
