摘要： A new 'cold' process for the recovery of elemental sulphur from contaminated elemental sulphur products is described. Elemental sulphur is recovered by froth flotation from: contaminated base pads of elemental sulphur blocks, stockpiles of contaminated elemental sulphur; contaminated elemental sulphur rejects from industrial handling and hauling; complex sulphur agglomerate, reject by-product from hot melting processes which is presently unprocessable and discarded (or as is otherwise referred to as 'sulphur crete melt residue'); contaminated products resulting from the exploitation processes using wells for the application of heat to reservoirs in order to recover elemental sulphur; and also from otl er sources of contaminated elemental sulphur in the oil and gas and other industries. This process comprises the steps of coarse screening, crushing, wet grinding, sizing, classifying. Then, the wet ground slurry at ambient temperature is treated by froth flotation, removing the elemental sulphur in the froth, and transporting undesirable contaminants to storage ponds or subsequent land reclamation. The initial elemental sulphur froth from the first stage of flotation is cleaned one or more times by reflotations. The cleaned elemental sulphur-bearing froth is then filtered to reinove excess water and to produce a filter cake.

摘要翻译：被描述为元素硫从单质硫污染的产品回收新的“冷”的过程。元素硫是通过泡沫浮选回收从：元素硫的块，被污染的元素硫的储存污染基垫; 污染元素硫从工业装卸和牵引拒绝; 复杂的附聚物硫，从热熔融过程拒绝副产品所有这是目前无法处理和丢弃（或以其它方式通过向称为“硫克里特熔化残余”）; 污染的产品从开采所得工艺使用井的热施加到以回收元素硫贮存器; 因此，从在油污染元素硫和天然气等行业的其他来源。该方法包括粗筛，粉碎，湿式粉碎，上浆，分级的步骤。然后，在环境温度下将湿地面浆料通过泡沫浮选处理，除去在泡沫中的元素硫，并输送不希望的污染物，以存储池塘或随后的土地开垦。从浮选的第一阶段的初始元素硫泡沫由reflotations清洗一次或多次。然后将清洁的元素硫承载泡沫被过滤以除去过量的水并产生滤饼。
