"Between 1978 and 1980, Canadian coal preparation plants produced between 18.6 and 22.5 x 106 tonnes of clean coal annually. Data based on samples taken at the ten operating washeries during the period indicated that the average industry-wide yield of 73.1% was achieved with an organic efficiency of 93.4% and that losses of saleable coal to the refuse amounting to 1.3-1.7 x 106 tonnes could be valued at close to $37.5 million per year"--Summary, p. v.
