How Current Density Affect the Cathode Deposit in Copper Electrowinning? In the copper electrowinning process, the copper plating rate increases with increasing current density. However, excessive current density gives rough, nodular cathode deposits and decreased copper purity. Therefore, each plant chooses its current density as a balance between these opposing factors. Maximizing current efficiency Current efficiencies in modern electrowinning plants maybe around 90 %. The unused current is wasted by: (a) anode/cathode shor

Acid Mist Suppression in Copper Electrowinning In the electrowinning of copper process, immersing metal cathodes and inert conductive anodes are employed in an aqueous solution of copper sulphate containing free sulphuric acid (CuSO4-H2SO4-H2O electrolyte). An electrical potential is applied between the anodes and cathodes, and pure metallic copper is generated from the electrolyte onto the cathodes. Copper is electrodeposited on the cathodes for about one week, after which harvesting is done while water dissociates into hydrogen i

What is the Purpose of Counter Electrodes in Electrochemical Reaction? Most electrochemical methods involve the use of three electrodes; namely the working electrode (WE), reference electrode (RE), and the counter electrode (CE) which is also called the secondary or auxiliary electrode. The three electrodes are connected to a potentiostat /galvanostat, which is an instrument that can perform both controlled potential (potentiostatic) and controlled current (galvanostatic) experiments. The potential drop near the other current-carry

What Factors Affect the Lifespan of A Water Heater? The local water quality is one of the factors that contribute most significantly to the performance and longevity of water heaters. Specifically, highly alkaline water will lead to the accumulation of scale, which will impact the efficiency of tankless and gas storage water heaters and can lead to decreased water hater life. Conversely, soft water increases the risk of corrosion, which can decrease equipment life by more than half if not properly mitigated. Increasing the lifetime
