Title:
PROCESS FOR PRE-CONCENTRATING AND/OR CONCENTRATING COPPER SULFIDE ORES, PRECIOUS METALS AND WASTEUSING GRAVITATIONAL CONCENTRATION TECHNOLOGIES
Document Type and Number:
WIPO Patent Application WO/2018/209455
Kind Code:
A8
Abstract:
The present invention relates to an ecological and mobile plant for recovering gold and copper, with simplified processes, which has devices and reduces the technical complexity of the operation, which is reflected in lower investment and operation costs. The plant can carry out eight types of process, which will be explained later on in the description. The plant and the types of processes operate using gravitational concentration methods, which do not use chemical reagents, particularly not mercury, which is a reagent widely used in small gold mining operations. In the use of these concentration technologies, an aspect to note is that it is feasible to work with relatively coarse particle sizes, in the order of 1 mm or more, which can be achieved with the use of crushers, and that these sizes retain less water in the tailings
