Copper sulfate (CuSO4) provides a source of copper ions. Sulfuric acid (H2SO4) makes the bath conductive and acts as a charge carrier. Chloride ions (Cl-) combine with the organic species to form a complex that slows down plating rate on selective areas.
Answer (1 of 3): The confirm of ore dressing process is closely related to the ore property to be chosen. It is also the basic referring conditions. It is the same with the copper ore dressing process. For example, there is a copper ore in Dexing, Jiangxi province. Its properties are as follows: ...

The study was performed on a copper sulfate solution that had a nominal concentration of copper ions of 500 ppm (mg/L) and a definite concentration of 0.5 M (NaCl) as supporting electrolyte. The initial pH of the electrolyte was normally about 2.5 (unless changed to other values) and adjusted by using either dilute HCl or NaOH pellets.
Three experiments were conducted to study Cu sulfate and tribasic Cu chloride (TBCC) as sources of supplemental Cu for poultry. In Experiment 1, 252 chicks were fed the basal corn-soybean meal diet (26 ppm Cu) supplemented with either 0, 150, 300, or 450 ppm Cu from Cu sulfate or TBCC for 21 d. Chic …
Adopting the roughing in the case of coarser mineral granularity, using the sodium carbonate, sodium silicate, copper sulfate, butyl xanthate as the reagent combination, then adopting closed-circuit flotation based on the condition of roughing, so that the gold concentrate with ideal grade and recovery rate can be obtained. 3.
Copper Sulfate absorbs water easily, forming a weak bond between the copper sulfate and five water molecules. This is written CuSO4 . 5 H2O. The name of this compound is "copper sulfate pentahydrate". But when copper sulfate is heated (as in a fire), these weak bonds are broken and the water evaporates.
Copper sulfate pentahydrate is a blue compound that forms striking blue crystals and dissolves readily in water. It's often used in agriculture, especially as a pesticide, soil additive and feed additive. It's also used in the manufacture of other copper compounds and in electroplating baths.
Repeat the experiment, however prepare two test tubes with copper sulfate solution at the same time. In each of them you will need to add 5 grams CuSO 4 *5H 2 O, so use the solution and the crystals from the main experiment. Stop after the 9th step in the instructions.

Copper sulfate CuSO 4 found its application in various fields of human activity. For instance, anhydrous copper sulfate can be used as a dehumidifying agent. Copper sulfate solutions may serve as an antiseptic and as a source for depositing copper on metals. It is also used in manufacturing high-purity metallic copper. Thus, copper sulfate is ...
Another sets of coarse finished (120 grit paper) specimens free from oxides were subjected to boiling in copper-copper sulfate -16% sulfuric acid solution for about 72 hours. This test was carried out according to ASTM 262 practice E. After boiling the specimens were bent through 180° and bent location
1. When weigh the crude copper sulfate crystal, we should first grind it in the mortar, otherwise it will be difficult and time consuming to weigh and dissolve. 2.

4) Continue heating until all the blue hydrated copper(II) sulfate has been converted to the white anhydrous powder. 5) Allow the dish to cool. Grind up any lumps that may be present. 6) Place the anhydrous copper (II) sulfate into a dry calorimeter and cover it. 7) Measure to the nearest 0. 1oC the temperature of 25.0 mL of water (contained in a
The sulfate analysis was corrected for the amount of sulfate present as CuSO4 so that the ordinates of figures 1 and 2 show the ratio of copper to solvent sulfate in the solution. As figure 1 indicates, the solubility of CuSO4 in pure H2SO4 is relatively low, but increases rapidly as the (NH4)2SO4 content of the solvent increases.
1. Introduction. A number of different hydrated forms of MgSO 4 ·nH 2 O (1≤n≤11) as well as three different polymorphs of the anhydrous MgSO 4 have been described from laboratory experiments (Table 1).Most of them have been found as minerals on Earth (Peterson, 2011), and recent space missions support the presence of significant quantities of Mg sulfates in soils and sediments of Mars (cf ...
Copper sulphate had no significant effect on the rate of adsorption of potassium n-butyl xanthate (PNBX) onto pyrite. Copper adsorbed irreversibly onto the pyrite when the latter was slurried in a copper sulphate solution. Copper sulphate had a significant effect on the maximum froth height obtained in static three-phase froth tests.
The blister copper anodes are immersed in an electrolyte containing copper sulfate and sulfuric acid. Pure copper cathodes are arranged between the blister copper anodes and a current of over 200A passes through the solution. This is driven by a low voltage of about 1.3V and so the process is safe. What happens in electrolysis?

In our lab, we heated copper sulfate pentahydrate (Cuso4 H20) after grinding it. Our observations included a color change from blue to white, which led us to believe it was a chemical change.
The practice has proved that the use of copper sulfate activation and butyl xanthate as the collector when preferentially flotation of copper can make the zinc-sulfur mixed ore contain 6.5% zinc and 40.29% sulfur, and the recovery rate of zinc and sulfur can reach more than 90% The separation and recovery effect is remarkable.
Nauseating metallic taste. Odorless. White when dehydrated. (NTP, 1992) CAMEO Chemicals. Copper (II) sulfate pentahydrate is the pentahydrate of copper (2+) sulfate. A bright blue crystalline solid. It is a hydrate and a metal sulfate. It contains a copper (II) sulfate.
Make a Saturated Copper Sulfate Solution . Stir copper sulfate into very hot water until no more will dissolve. You can just pour the solution into a jar and wait a few days for crystals to grow, but if you grow a seed crystal, you can get much larger and better-shaped crystals.
