Recovery of Copper from Copper ores by roasting at different temperatures The experiments showed that the untreated raw oxidized copper ore show significant leaching which is 9.5% for salineThe recovery achieved from the untreated ore was 50%, while acid pretreatment for 20 min increased the recovery to 70%. The observations by Ramonotsi [ 17 ] are consistent with the findings of the earlier study by Luszczkiewicz and Chmielewski [ 18 ] on sulfuric acid pretreatment of copper sulfide middlings in the flotation of carbonate ores.Potential Processing Routes for Recovery of Platinum Group

Current Status of Copper-Ore Processing: A Review
The head grade of copper in the ore is 1–2% and the oxidation state is ~60% [ 26 ]. The decision to use the combined technology for processing ores with the ultimate recovery of copper into a bulk concentrate (~90%), its low copper content (~5–6% copper), and the decrease in copper loss with tailings was taken after numerous tests.That constitutes an increase of more than 20% compared to the cumulative copper recovery of less than 30% obtained when using SIPX and sulphidisation to float copper oxide ore (Corin et al., 2017The recovery of oxide copper minerals from a complex copper ore

How to Process Copper Ore: Beneficiation Methods and Equipment
Before the beneficiation of copper ores, crushing and grinding are required. The bulk ores are crushed to about 12cm by a jaw crusher or a cone crusher. Then the crushed materials are sent to the grinding equipment, and the final particle size of the copper ore is reduced to 0.15-0.2mm. Copper ore crushing process. 1.Sulfidic copper–lead–zinc tailings can pose a significant environmental threat, ranging from generation of acid mine drainage (AMD) to dam failures. On the other hand, they can also be considered as low-grade ore resources for zinc and copper provided that novel economically feasible metal extraction and metal recovery techniques are Recovery of Copper from Ammoniacal Leachates by Ion Flotation

The flotation of sphalerite mine tailings as a remediation
According to the flowsheet reported in Fig. 8, Xiao et al. (2012) carried out flotation tests on oxidized Pb-Zn ore, with 2.84% Pb and 3.23% Zn grades, from Lanping (China). The oxidation rate of the minerals was high (90.85% for Pb and 87.9% for Zn). Evaluation of the possibility of copper recovery from tailings by flotation through benchCopper oxide ore has a complex composition, and a low recovery rate is often achieved via the traditional sorting method. A new combined process of flotation–high-gradient magnetic separation–leaching is proposed here to recover copper minerals.

Enhanced Gold Recovery from Alkaline Pressure Oxidized
Pressure oxidation is a widely accepted method to treat refractory gold ores. Gold recovery is generally lower from alkaline than acidic pressure oxidation discharge due to passivation and incomplete oxidation of mineral. Gold ore from Goldstrike, NV, is a typical refractory gold ore containing sulfide and carbonaceous matter. Alkaline pressure The copper ore in Chilean copper porphyry deposits is often associated with molybdenum minerals. This copper–molybdenum (Cu–Mo) sulfide ore is generally mined from various locations in the mining site; thus, the mineral composition, oxidation degree, mineral particle size, and grade vary.
