Re-election law only recovery of ore with a certain hand-selected gold-bearing 259 VIII (often higher) free gold particle size, ultra-fine grain and piece of foil-like gold by the ground after spreading chute. In this, the heavy minerals will be lost. Deposited. Then placed in intraday grinding, until gold was re-election law for coarse gold concentrates should not be in a straight silver amalgam form and other mineral separation, then the mercury is then smelted into gold bullion, which still contains other heavy mine homogeneous heating the gold separated. The resulting coarse gold silver approximately matter. Therefore, 15-40% of the solids content of about 30% and adding a small amount of cyanide. Sodium and sodium hydroxide under the conditions, grinding in a ball mill because the tailings the auriferous still up to 12g / t, therefore, a 12h procure gold particles further dissociation and its surface net some percolation leach cyanidation of the plant from the leaching solution with zinc powder. Then added mercury (than gold, the silver component amalgam replacement further recovery of gold.

In the brick process, need materials will be broken after grinding again after baked process, how to choose crusher to suit the brick ? Hxjq heavy industry as a professional production crusher and ball mill of mine equipment enterprise, will tell you in the following according to different raw materials, choosing appropriate crusher and grinding mill.

First of all, clay sintering brickyard should choose broken equipment in is better, in the actual production of should also be screening , so that can not only achieve forming request, and can achieve the dry body requirement, also can achieve reasonable sintering mesh and. Clay baked brick raw material with reasonable grading, also is one of the conditions of producing quality products. Clay and gangue, shale physical performance has great difference, clay there is great natural moisture, be in usually, mining out raw material can not immediately crushing, screening, the characteristic of clay to crush equipment selection and process puts forward special requirements, crushing equipment not only to reasonable selection and installation process and layout must conform to the actual production needs, the only way to achieve the expected effect of production.

Secondly, because of the difference raw materials, production process decorate also not the same, the selection of crushing equipment are needed in each according to, clay brickyard to see, hammer mill, roll machine, cage mill, fan mill, impact crusher, high-speed fine grinding of roll machine, etc are in different production process was selected, improper selection, you can not play equipment of the actual production effect. Usually, clay is divided into high plastic, plastic, low plastic 3 kinds of different raw material, also have each different molding, drying, baking properties, clay sintering brickyard if choose the fan mill, ball mill these fine grinding equipment in the production of the crushing equipment play the superior performance, because fan mill is winnowing particles into the equipment technological requirements;
