Abstract
A method is shown for briquetting quicklime fines. A source of quicklime or dolomitic quicklime fines is combined with a binder in the form of a pseudo-plastic carbon containing material which will deform under briquetting conditions of elevated temperature and pressure and flow and which will also return to a solid phase and bind the quicklime fines upon cooling. An external force is applied to the mixture of fines and binder, as with a briquetting machine, sufficient to form the mixture into a briquette having requisite strength and durability characteristics. Suitable classes of carbon containing materials include Gilsonite.RTM., a solid coal tar pitch and recycled plastics such as polyethylene and polypropylene.
