The extent of gangue mineral dissolution was minimal in all three experiments (Fig. 4). Acid consumption per pound of copper was relatively constant in all three experiments, despite changes in the rate of limonite dissolution the 20 and 40 g/L (0.19 and 0.37 oz/gal) experiments.get price

Ore and Gangue Mineral Types The ore minerals chrysocolla and malachite responded to leaching in much the same manner. The rates of dissolution were such that it generally took 4 to 8 days to reach the ultimate economic recovery on a minus ½-inch ore, get price

Chrysocolla is a sharply colored mineral. Its color can be among the brightest shade of blue and green, and is caused by its copper content. Chrysocolla is often coated by a drusy layer of glossy clear Quartz, or intergrown together with the Quartz. The chemical formula for Chrysocolla is not clearly defined, as it contains a varying substitution of elements and water content in its chemicalget price
minerals present in the ore. Gangue minerals such as biotite and chlorite consume acid together with copper-bearing minerals such as chrysocolla and malachite. Acid consumption is affected by the rate of acid application and the particle size. Some gangue minerals undergo alterations and cause precipitate formation during acid leaching. Otherget price

If the gangue mineral in an iron ore is predominantly quartz, reverse flotation is usually used in the cleaning stage to improve the concentrate grade. Figure 9.13 presents a typical flow sheet for processing an oxidized iron ore containing about 30% Fe using a combination of SLon magnetite separators and reverse flotation. The ore is mainly composed of magnetite, hematite, martite, and quartz.get price
The primary ore minerals are native gold, chrysocolla, and malachite. Gangue minerals include specular and earthy hematite, quartz, barite, fluorite, calcite and manganese oxides. Although open-space filling textures are locally abundant, most of the economic mineralization occurs as fault-controlled replacements in calcareous sediments.get price

Copper processing Copper processing Ores: Principal forms in which copper ores are found include native copper, porphyry copper, massive deposits, and mixed ores. Native copper is simply the metal found unadulterated in nature. Occasionally copper is still found in its native form, but more frequently it is mixed with other minerals, some of which may have value themselves.get price
Increased residence time of the collector in the pulp prior to flotation substantially degraded the recovery and lowered the grades collected. Magnetite was present as a gangue mineral in both the Clifton chrysocolla and Gosford sand used in the flotation experiments. The iron was collected at recoveries of up to 70%, at grades of less than 7%.get price
Most copper ores contain only a small percentage of copper metal bound up within valuable ore minerals, with the remainder of the ore being unwanted rock or gangue minerals, typically silicate minerals or oxide minerals for which there is often no value. In some cases, tailings have been retreated to recover lost value as the technology for recovering copper has improved.get price

Copper minerals can be divided into three groups: (i) primary sulphide minerals (e.g. chalcopyrite, bornite, and enargite); (ii) oxides, formed by weathering of primary sulphides (e.g. cuprite, malachite, chrysocolla and covellite); and (iii) secondary sulphides (e.g. chalcocite and covellite) formed from copper leached from near-surfaceget price

oxide minerals, such as malachite or chrysocolla, depend on the composition of the gangue or fluid. The iron liberated during the alteration sequence can remobilized and form goethite or limonite.

In this study, ethylene diamine phosphate (EDP) was employed as an activator to improve the sulfidization and flotation of chrysocolla. The micro-flotation experiment results indicated that EDP could greatly increase the flotation recovery of chrysocolla. BET and TEM measurements confirmed that the porous structure of the chrysocolla’s surface would lead to large amounts of the reagents.get price
