The flotation-acid leaching process for complex low-grade copper oxide ores comprises the following steps:
The raw low-grade copper oxide ore is crushed, ground, and prepared into ore pulp;
Flotation reagents are added to the above ore pulp, and one stage of roughing and one stage of scavenging are conducted to obtain copper oxide concentrate and tailings;
The obtained copper oxide concentrate is prepared into ore pulp, then concentrated sulfuric acid is added for leaching under agitation. Solid-liquid separation is performed afterwards to produce copper-bearing leachate and leaching residue.
This process integrates flotation and acid leaching to treat low-grade copper oxide ores. The low-grade copper oxide ore is subjected to one-stage roughing and one-stage scavenging flotation in the presence of a sulfidizing agent, which realizes the preliminary separation of high acid-consuming silicate and carbonate minerals (including chlorite, dolomite, talc, etc.) from copper sulfide minerals in the ore. Combined with the subsequent acid leaching process, copper leaching can be achieved at a relatively low acid consumption. This process overcomes the defects of existing technologies for copper enrichment from low-grade copper oxide ores, such as complex process flow, high reagent consumption and high production cost.

gold recovery machinesilver/gold recovery machine,silver/gold refining equipment,silver/gold refining equipmentInstruction Of Gold Recovery Machine:
The new version gold recovery machine an intelligent touch screen, low-voltage extraction technology, supports fully automated intelligent operation, and offers automatic/manual mode.

The JQ series uses electrolysis to adsorb gold, silver, copper, and other precious metal ions from solutions onto the cathode. Once a certain weight is adsorbed, the precious metal sheets (gold, silver, copper, etc.) are stripped from the cathode. This equipment enables safe and efficient refining and recovery of various solutions containing gold, silver, or copper, ultimately converting the ions in the solution into pure precious metal form.
Product Advantages:
1、High-efficiency recovery of gold, silver, copper, and other valuable metals;
2、Precious metal purity ≥ 99%, with an ion recovery rate ≥ 99%;
3、Low-voltage extraction, highly efficient, and odor-free.
