Roll-press briquetting Squeezing value from lime

摘要

In many chemical and mineral processing industries, once money has been invested both in mining (or buying) the raw material and in the equipment and energy needed to prepare it for sale, discarding fines will not only waste part of that investment, but might even add cost in transportation and possibly dumping charges. So the question becomes, how can fines be turned into a revenue-generating asset? One answer arises in the example of quicklime processing. This article is intended to help the reader explore the potentials of briquetting by providing a general introduction to roll-type briquettes, how they work, and the various factors that affect their application to quicklime fines and other areas of mineral processing.
