Description

Oxidation solution Gold Concentrate under Normal Pressure precipitation recovery system

Technical field

This utility model relates to mineral resources ore dressing field, specifically a kind of oxidation solution aurin Ore deposit precipitation recovery system.

Background technology

Gold Concentrate under Normal Pressure recovery process flow process of the prior art is as follows: Gold Concentrate under Normal Pressure through one-level, two grades Pool together after biological oxidation, and after the backwash step by step of three concentrators, the biggest portion Parting concentrate flows to cyaniding workshop and carries out cyaniding, and liquid (the i.e. oxygen produced in backwash process Change liquid) need to be flowed to by the overflow passage of every concentrator the buffer-precipitation pond of neutralization department is entered Row buffering precipitates, and its objective is that the Gold Concentrate under Normal Pressure making to suspend in oxidation solution precipitates, reduces and run off, Improve the response rate of gold.As it is shown in figure 1, the oxidation solution Gold Concentrate under Normal Pressure precipitation in existing technological process Recovery system mainly includes a buffer-precipitation pond and a neutralization chamber, and oxidation solution flows directly into slow Rush in sedimentation tank, then flowed in neutralization chamber by pumping action, then in neutralization chamber, add white lime enter Row neutralizes, and the mine tailing finally produced is reclaimed, but finds in actual production is put into practice, this Although precipitation recovery system has certain precipitation, but effect is not highly desirable, still has one Quantitative Gold Concentrate under Normal Pressure runs off, and finds, why can produce this after repeatedly observing and testing Situation, the oxidation liquid measure produced mainly due to every day is bigger, thus results in inflow buffering heavy The oxidation solution flow velocity in fall pond is relatively big, and impulsive force is relatively strong, so, not only makes oxidation solution not foot Enough sedimentation times, and the Gold Concentrate under Normal Pressure settled suspends under the impact of oxidation solution flow velocity Getting up, thus cause loss, the oxidation solution Gold Concentrate under Normal Pressure precipitation in the most existing technological process reclaims System needs to make improvements.

Utility model content

The purpose of this utility model is to provide a kind of oxidation solution Gold Concentrate under Normal Pressure precipitation recovery system, logical Spend the sedimentation time increasing multiple efficient sedimentation tank prolongation oxidation solution, thus ensure in oxidation solution Gold Concentrate under Normal Pressure fully precipitates, and the most effectively slows down oxidation solution flow velocity, it is to avoid the most deposited aurin Ore deposit Eddy diffusion.

The purpose of this utility model is achieved through the following technical solutions:

A kind of oxidation solution Gold Concentrate under Normal Pressure precipitation recovery system, including buffer-precipitation pond, neutralization chamber and many Individual efficient sedimentation tank, wherein said multiple efficient sedimentation tank are sequentially connected in series by overflow passage, oxygen Change liquid intake line to communicate with an efficient sedimentation tank of outermost end, the efficient sedimentation tank of the other end Then being communicated with described buffer-precipitation pond by pipeline, pipeline is passed through with described in described buffer-precipitation pond Neutralization chamber communicates, and is provided with pump on the pipeline that described buffer-precipitation pond communicates with described neutralization chamber.

The quantity of described efficient sedimentation tank is two.

Described efficient sedimentation tank is rustless steel efficient sedimentation tank.

Described oxidation solution intake line is gravity line.
