STUDY ON PYRITE CINDER (1st Report)

REMOVAL OF COPPER AND SULPHUR BY MECHANICAL DRESSING.

Abstract

The pyrite cinder with the decreased copper and sulphur content may be obtained either by sizing or floatation. The alternative should be decided in the following way:
(1) Sizing is preferred in ease of tlhe presence of much roasting kernels.
(2) Floatation is preferred in case of the absence of roasting kernels.
