· The pulp was then dried in a stove at 60 °C and ground with an agate mortar. In batch experiments, a pulp particle size lower than mm was used. Synthesis of gold nanoparticles The experimental method consists of mixing 50 mL of aqueous solution of tetrachloroaurate with sugar beet pulp (5 g/L) and stirring the mixture at room temperature.

A paper published by L. Elsner in 1846 first correctly identified the chemical reaction that forms the basis of all gold cyanide leaching processes: 4 Au + 8 NaCN + O 2 + 2 H 2 O → 4 Na [Au (CN) 2] + 4 NaOH. The equation is well known, but the successful appliion of this reaction in a gold mining operation is rarely straightforward.

where Cl is the gold concentration in the liquid phase, Cc is gold content in the activated carbon, Cc * is the maximum gold content of the activated carbon, and k c and k d are empirical kinetic constants of adsorption and desorption for gold. Note that under equilibrium conditions (R CB =0) this model becomes the classical Langmuir equation, where A = Cc * and B = k d /k a.

A survey of leaching systems for the dissolution of gold has been undertaken and their advantages and disadvantages evaluated both from their effectiveness at leaching and their compatibility with carbon inpulp (CIP) and resininpulp recovery. In the near future it is almost certain that cyanidation in some form will remain the leaching system although .

Carboninpulp was used to extract gold and silver from the solution. After elution with thiourea–butanol and cementation with zinc dust, the final PM concentrate assayed 45% Cu, 30% Ag, and % Au. The process was piloted at a scale of 1 t/d of calcine by Noranda (Rosato et al., 1990). Another approach to recover gold and silver from jarosite leach residues from the zinc .

gold plants where uranium and gold are recovered from the same milled ore. Uranium is leached in acidic solution (pH 1 to 2), and any aurocyanide pre sent in solution in the feed to the uraniumleaching plant will precipitate as AuCN, and will be lost with the solid residue from the plant. This has been a major impediment to the development of processes for the simultaneous leaching .

· Activated carbon in contact with a pulp containing gold can typically recover more than % of the gold in the solution in 8 to 24 hours, depending on the reactivity of the carbon, the amount of carbon used and the mixer's efficiency. The loaded carbon is then separated from the pulp by screens that are air or hydro dynamically swept, thus preventing blinding by the .

gold extraction plants. In the carboninpulp process adsorption occurs after the leaching cascade section of the plant, and in the carboninleach process leaching and adsorption occur simultaneously. In both processes the activated carbon is moved from one tank to another in countercurrent with the ore pulp until the recovery of the loaded carbon in the first tank. This .
