Technique for fast preparing spongy copper

Abstract

The invention relates to a technology of rapidly manufacturing copper sponge. Raw copper ores are first put into a spray pond; the bottom of the spray pool is communicated with the upper opening of a purifying pond; the overflow port of the purifying pond is communicated to a water pump pool; a feed liquid inlet of a liquid recycle pump is in the water pump pool; and a liquid inlet is communicated with a spray system; and the upper part of the spray pond is provided with a original spray system, spray sulfuric acid solution, ammonium chloride solution, and potassium permanganate solution orderly by the original spray system to raw copper ores; the three solutions are discharged into the purifying pond through a liquid outlet at the bottom of the spray pool, and mixed in the purifying pond before overflowing into the water pump pool; a recycle pump in the water pump pool sends the mixed solutions into the spray system for spraying 24 to 40 hours continuously; during spraying, iron filings are added in the purifying pond; after continuous spraying, the mixed solutions in the purifying pond are discharged, and the deposit in the purifying pond becomes copper sponge. The invention is a technology of rapidly manufacturing copper sponge with low production cost and high copper recovery rate.

Description

1. Technical field [0001] The invention relates to a metal preparation process, which is a process for preparing sponge copper by rapidly decomposing primary copper ore raw materials with a catalyst. 2. Background technology [0002] At present, primary copper ore raw materials (natural ore) contain silicon content as high as 80%, and it is difficult to melt primary copper ore raw materials by pyrometallurgy to prepare copper. If copper is prepared by washing method, the copper recovery rate is only 55%. -60%, not only large investment and high production cost, but also cause a lot of waste of resources. 3. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies of the prior art and provide a process for rapidly preparing sponge copper with simple production process, low cost, small investment and high copper recovery rate. [0004] The purpose of the present invention can be achieved through the following technical solutions...
