copper leaching system

copper oxide ore leaching and electrowinning system

1、Customer demand

The metal copper in copper ore is extracted by physical and chemical methods, and a theoretical and practical process is found for extracting copper from copper ore.

2. Basic customer data

Feed type	Copper production	Product shape	process mode	Solution copper content	Effluent copper content
20% copper ore concentrates powder	100 kg	Copper sulfate solution	Batch processing	5-20%	20g/L
Copper sulfate solution	100 kg	Electrolytic copper plate	Batch processing	10-40g/L	2g/L

3.Process introduction

The experiment was mainly carried out in three steps:

In the first step, the copper metal in the copper ore is dissolved in the liquid, and the solid copper metal is converted into the free ion state;

The second step, the solution of dissolved copper is filtered to remove impurities;

The third step is to extract and purify the copper in the copper containing solution. The result is a high purity copper sheet.

4.Experimental Process:

1.Configure the concentration of about 10% to 15% concentration of dilute sulfuric acid

solution standby.

2.A certain amount of copper ore is weighed and crushed, and the crushed copper ore powder is placed in dilute sulfuric acid. After the copper ore is put into dilute sulfuric acid,

a violent reaction occurs in the solution, some gas emerges, and the copper ore slowly dissolves. The color of the potion turns cloudy.

3.Add an appropriate amount of oxidant to accelerate the dissolution of copper in the ore powder.

4.After about 1 hour,the solution appears stratified, green clear liquid appears on the upper layer,and very colored insoluble solid or sludge appears on the bottom.

5.The precipitation was filtered and separated, and the green liquid was filtered out.

6.The copper content of the green filtrate was analyzed, and the concentration of copper ion reached 40g/L. High copper content.

7.The electrolysis experiment was carried out on the green copper filter liquid, with the filter

liquid as the electrolyte, titanium plate as the anode and stainless steel plate as the cathode.

8.A certain intensity current is applied to the anode and cathode plate for electrolysis, and a

copper substance appears on the cathode plate and is attached to the cathode stainless steel plate. Continue electrolysis.
