My said disintegrator, wherein the material, instead of being crushed or ground, is subjected to the whipping action of numerous flexible blades secured to the rapidly-revolving cone, by which operation the earth is speedily reduced and the gravel cleaned,Clay Beneficiation Plant is admirably adapted to do this work thoroughly and quickly. The reduction is perhaps most advantageously done when performed in the presence of heat, because many of the larger lumps of placer dirt may pass through the drier without being perfectly dried, and hence when broken up in a warm disintegrator the small portions thereof are readily deprived of the small amount of moisture they contain.
To obtain this warmth in the disintegrator, the clay, &c., may be conducted to it directly from the drier and before it has parted with the heat received therein; or a blast of heated air may be supplied through the pipe II for the purpose, or both the heat carried in the material (the outer shell of the lumps will naturally be overheated) and the warm blast be used.Clay Grinding Machine Prices. The final drying thus received,while the earth is being reduced to a fine condition, will also be expedited by the current of air passing through the disintegrator, and in ex ceptional cases, in dry climates, such current will be sufficient to obtain some of the benefits ofmy invention. After being thus pulverized and dried the material is ready to be acted upon by the concentrator, and is fed thereinto. In this concentration the material may be agitated and the gold allowed to fall, by its superior gravity, into collectingpockets; or the separation of the gold from the dirt may be effected in any other known way of concentration by dry methods. A further separation of the finer gravel and the earth may take place at the disintegrator.
In some cases, when the dry season is protracted, the artificial drying may be dispensed with; but I do not advise such course even in g dry seasons, if fuel to operate the drier is to be had. \Vhere the drying is coupled with the other parts of the operation, the mining can be carried on the year round without diffieull'y.I claim The improvementin the method of dry concentration of gold from alluvial deposits, consisting in first subjecting the deposits to artificial heat, then disintegrating the dirt and cleaning the gravel without crushing or grinding it, and then separating the gold, substaxr tially as specified.
