Non-process element mass balance improves recaust and lime

Non-process element mass balance improves recaust and lime

Filtered lime mud at the Elk Falls mill had low solids content and was dark green. Along with high NPE dead load, this caused additional kiln fuel costs of nearly $300,000/year. An NPE mass balance was obtained, using composite samples from fifteen different process streams. Kiln fuel oil was a significant source of phosphorus, iron and zinc. NPE specifications for lime rock, fuel oil, salt
