Sposób wytwarzania pelletu polega na tym, że do węgla brunatnego lub kamiennego w ilości od 65% do 98% wag. o uziarnieniu poniżej 10 mm i wilgotności od 3% do 40% dodaje się kredę jeziorną w ilości od 2% do 35% wag. o uziarnieniu poniżej 10 mm, wilgotności od 3% do 40% i zawartości węglanu wapnia powyżej 50%, przy czym stosunek molowy wapnia w kredzie jeziornej do siarki w węglu brunatnym lub kamiennym wynosi od 2 do 5.The method of producing pellets consists in the fact that for brown or hard coal in an amount of 65% to 98% by weight. with a grain size below 10 mm and humidity from 3% to 40%, lake chalk is added in an amount of 2% to 35% by weight. with a grain size below 10 mm, humidity from 3% to 40% and a content of calcium carbonate above 50%, with the molar ratio of calcium in lake chalk to sulfur in brown or hard coal being from 2 to 5.
