Extraction of Silver Silver Anode - Scribd

mainly by electrolytic refining, as mentioned earlier dore metal obtained from the copperslimes can be refined by moebius and thum-balbach processes in these processes the purity level of silver reaches from 80-98%to 99.99%. MOEBIUS PROCESS The electro refining silver in a Moebius cell is similar. to that of electro refining but here the anode is用户评级: 5/5

Electrorefining - an overview ScienceDirect Topics

3.6 Electrolytic Refining. The Betts electrolytic refining process generally uses an aqueous electrolyte of hydrofluorosilicic acid H 2 SiF 6 at a concentration of 90–130 gl −1, lead at 70–100 gl −1 and a temperature of 40 & 176;C. Alternative electrolytes are sulfamic acid HSO 3.NH 2 and fluoroboric acid HBF 4 . Electrolyte addition agents include lignin sulfonate and glue.

Electrorefining - an overview ScienceDirect Topics

During the electrolysis the metals present in the anode, which are of lower electrochemical activity than copper, chiefly silver, tellurium, gold, and traces of platinum, are precipitated as slimes on the floor of the electrolysis cells as they are released from the anodes Table 13.3 . Any mercury, which is frequently present in the ore, is mostly vaporized in the hot smelting stages prior to electrorefining.

Electrolytic Refining - Mineral Processing and Metallurgy

Basis of Electrolytic Refining MethodsElectro-Refining and electro-winningElectro-Refiningelectro-winningAll electrolytic operations depend upon two basic factors: the first is the volume or quantity factor which is related to amperes; the second is the energy or pressure factor which is related to volts. The quantity of metal deposited from an electrolyte is in accordance with the laws enunciated by Faraday, which state in effect: 1 that the quantity is proportional to the number of ampere-hours, and 2 that a given number of …在911metallurgist.com上查看更多信息

Difference between electrolytic reduction and electrolytic

In electrolytic reduction current is passed through the metal oxide to reduce it to pure metal whereas in electrolytic refining the impure metal is converted into pure metal. Some of the differences are given below: 1 In electrolytic reduction graphite electrodes are used which are of same size. in electrolytic refining the anode is made of

Electrolytic refining - NCERT help

Electrolytic refining: It is the process of refining of metal in which impure metal is made the anode and a thin strip of pure metal is made the hode. A solution of metal salt is used as an electrolyte. The apparatus is shown in the figure given below. When electric current is passed through the electrolyte, the impure metal from the anode is dissolved in the electrolyte and an equal amount of pure metal from the electrolyte …
