METHOD FOR RECOVERY OF COPPER FROM SULFIDIC ORE MATERIALS USING SUPER-FINE GRINDING AND MEDIUM TEMPERATURE PRESSURE LEACHING |
| 摘要 |
<p>The present invention relates generally to a process for recovering copper a nd other metal values from metal-containing materials using controlled, super-fine grinding reducing the particle size to P98 less than about 25 microns and medium temperature (140-180.degree.C) pressure leaching. Processes embodying aspects of the present invention may be beneficial for recovering a variety of metals such as copper, gold, silver, nickel, cobalt, molybdenum, rhenium, zinc, uranium, and platinum group metals, from metal-bearing materials, and find particular utility in connection with the extraction of copper from copper sulfide ores and concentrates.</p> |
