In the electrolytic refining of copper the more electropositive impurities like Fe, Zn, Ni, Co, etc. dissolve in the solution and less electropositive impurities such as Ag, Au and Pt collect below the anode in the form of anodic mud. The correct option is A.
Intuitively speaking, the final mass of the copper deposited on the cathode is lesser than what youd expect because there is less of the copper available. This is because some of the mass of copper is replaced by zinc, decreasing the total amount
Electrolytic refining is a process of refining a metal mainly copper by the process of electrolysis. As far as the mechanism of the process is concerned, during electrolysis, a large chunk or slab of impure metal is used as the anode with a thin strip of pure metal at the cathode.
Melting and Refining Technology for Copper Produced from Scrap Charge Our copper refining technology allows the use of higherimpurity charge materials, and still produce premium quality refined copper. In some applications, copper produced by this method may compete with copper that underwent electrolytic refining.
During the process of electrolyte refining of copper, some metals present as impurity settle as 39anode mud39. These are A. Sn and Ag. B. Pb and Zn. C. Ag and Au. D. Fe and Ni. November 22, 2019 Niti Vas. Answer. In Electrolytic refining, the impure metal is made to act as an anode.

The impure metal is made anode while a thin sheet of pure metal acts as a cathode. In electrolytic refining of copper, electropositive impurities like Fe, Zn, etc dissolve in the solution and less electropositive impurities like Ag, Au, etc collect below the anode. Option 1 This option is incorrect. Option 2 This option is incorrect. Option 3
Refining of metal is one of the processes which involves separation of impurities like sand particles, other metals etc. from the metal of choice. Therefore, refining of metal comes under the science of study physical and chemical properties of the metal which refers as 34Metallurgy34.
In refining copper, the metal is melted down in a reverberatory furnace in a more or less oxidizing atmosphere and then further subjected to an oxidizing smelting in order to eliminate the common impurities, most of which have a stronger affinity for oxygen than has these operations some of the copper is oxidized to cuprous oxide and dissolved by the metal bath.
8.During the process of electrolytic refining of copper, some metals present as impurity settle as anode mud. These are 2005 1 Sn and Ag 2 Pb and Zn 3 Ag and Au 4 Fe and Ni Ans.3 Crude Cu contains Au and Ag as impurities.
During the process of electrolytic refining of copper, some metals present as impurity settle as anode mud These are. Sn and Ag. Pb and Zn. Ag and Au. Fe and Ni. C. Ag and Au. 238 Views. Answer. 2. Heating mixture of Cu 2 O and Cu 2 S will give. Cu SO 2.
Copper processing Copper processing Roasting, smelting, and converting Once a concentrate has been produced containing copper and other metals of value such as gold and silver, the next step is to remove impurity elements. In older processes the concentrate, containing between 5 and 10 percent water, is first roasted in a cylindrical, refractorylined furnace of either the hearth or
During the process of electrolytic refining copper, some met Practice free questions on Transition Elements d and f block, Chemistry, JEE Main. SimplyLearnt. During the process of electrolytic refining copper, some metals present as impurity settle as anode mud. These are.
In electrolytic refining, the crude metal to be refined is made the anode and the pure metal is deposited on the cathode may be a pure strip of the metal itself or some other metal and electrolyte should contain an ionizable salt of th
In the electrolytic refining of copper the more electropositive impurities like Fe, Zn, Ni, Co, etc. dissolve in the solution and less electropositive impurities such as Ag, Au and Pt collect below the anode in the form of anodic mud. The correct option is A.
The Electro Refining Process the process must be designed to handle a variablequality metal feed and lead to a concentration of all the metals present in a form which can be treated further. Electrorefining often provides a particularly high purity of metal. voltage is applied to the electrodes to cause oxidation of copper metal at the
