Abstract
 

This study is a follow-up to a literature study of Alberta limestones to evaluate their potential as a source of calcium carbonate paper filler. The Government of Alberta is encouraging the establishment of a fine-paper mill in the province, and one of the principal raw material requirements is a white mineral filler. The province lacks kaolin, the most common paper filler used, but has extensive deposits of limestone, which can substitute for kaolin in the alkaline paper-making process.

The literature study (Hamilton, 1968) determined that Alberta limestones in general are grey-coloured and of insufficient purity for filler use. However, a few localized carbonate rock occurrences of exceptionally light colour were identified. These were recommended for field checking, sampling and laboratory tests to evaluate their filler potential. The present study carries out those recommendations.
