silver recovery using sodium sulphide. Sodium Cyanide is a deadly poison which is widely used in the mining industry. It is used as the leaching agent (lixiviant) in the recovery of gold and silver from mined ore. It is a white powder which is readily soluble in water.

A method is provided for extracting silver from a silver sulfatebearing substance, such as oxide materials, metal or metal sulfate mixtures containing silver sulfate which comprises subjecting...
The authors 16,17 showed that in neutral and weakly acidic sulphate media, the silver passivation is attributed to the formation of a silver sulphate layer. The aim of the paper is to study the influence of the concentrations of sodium sulphate and potential sweep rates on the anodic oxidation of silver under potentiodynamic polarization.
Sulphate removal from sodium sulphaterich brine using barium hydroxide and recovery of the barium salts has been investigated. The sodium sulphaterich brine treated with different dosages of barium hydroxide to precipitate barium sulphate showed sulphate removal from g/L to less than 400 mg/L over 60 min using a barium to sulphate molar ratio of
#0183;#32;For mother liquors of both companies the sodium sulfate recovery is over 98% when the alcoholliquor volume ratio is 7:3. When the H 3 BO 3 concentration in the liquors is diminished by cooling and the liquors mixed in a 4:6 alcoholliquor volume ratio, the Na 2 SO 4 recovery is higher than the one obtained without cooling.
Thus, with the method of detecting the cyclic potentiodynamic polarization curves it is shown that complicated electrochemical reactions occur in sodium sulphate solution using silver electrodes, in the anodic area silver oxidation with formation of oxides and sulphate of silver takes place, and in the cathodic area oxygen compounds and silver sulphate regenerate.
Silver Recovery with Sodium Sulfide The silver is precipitated as silver sulfide by the ad ition of sodium sulfide to the used fixing bath. Acid fiXing baths are first neutralized with caustic soda to prevent unpleasant fumes of hydrogen sulfide. (1) Weiner R. Zeitschrift fur elektrochemie Vol. 45 .

#0183;#32;Recovery of sodium sulfate from farm drainage salt for use in reactive dyeing of cotton. The recovered sodium sulfate samples, with purities ranging from 67 to %, were compared with commercially available sodium sulfate used in reactive dyeing of cotton fabrics.
Reaction type: double replacement precipitation. Most precipitates are formed in a doublereplacement reaction. Both AlNO3 and Na2S are soluble in water. First, Write
sodium sulphate solution using silver electrodes, in the anodic area silver oxidation with formation of oxides and sulphate of silver takes place, and in the cathodic area oxygen compounds and silver sulphate regenerate. These and other data received from the previous researches 79,22 form the theoretical basis of the electrode processes, occurring in the
When sodium hydroxide reacts with silver nitrate silver hydroxide is precipitated which is white in colour and NaNO3 remains ionized state in aqueous solution. The reaction is given below: NaOH(aq)+ AgNO3(aq) = AgOH(s) + NaNO3(aq)

complexes, and the sodium sulfate facilitates solution of the anode. Neblett(2) mentions several methods by which the silver in a used fixing bath may be recovered: Silver Recovery with Sodium Sulfide The silver is precipitated as silver sulfide by the ad ition of sodium sulfide to the used fixing bath.
