The equipment is new complete equipment used in gold trade to recover gold from the gold-carrying carbon. It is suitable for desorption and electrolysis of gold-carrying carbon with different grades. The desorption is an intermixture of 1~2% sodium cyanide and 1~4% sodium hydroxide. The desorption solution is pumped to the heater by circulating pump and heated to the desired temperature. Then the solution flows downward to the bottom of desorption column, through the gold-carrying carbon in the column and upward to the top of it. During flowing, the solution strip gold from the carbon (at this stage the solution containing gold is called as pregnant solution). The pregnant solution runs out from the top of the column and into the electrolytic cell. In cell, the gold in the solution is electrically deposited in the steel wool of the cathode frame, and the rest (called as lean solution) flows back to desorption solution cell and recycled.
The gold mud containing rich gold and silver is taken out of desorption cell and transported to the separation section.

Solar water pump consists of solar panel system, PV water pump controller system and pump.
1. Solar panel system: Solar arrays are in series-parallel of solar modules; Transfer the solar energy power to electricity to supply power for pump system.
2. Photovoltaic water pump controller system: It regulates all the pump system, turning instable DC voltage of solar panel system into stable DC voltage for pump, and regulates the output current in according with sunshine intensity to achieve maximum power point tracking(MPPT), maximizing the use of solar energy.
3. Solar pump system: It consists of pump body, motor, water pipe, cable, protection devices, water level sensor.
Application:
The solar pumps can automatically work in the day, while the sunshine is lower. So it is suitable for irrigation, garden, fountains, family, pastoral grasslands, mountain, especially working in the areas without electricity supply.
Products feature:
1. Water pump controller system has complete electrical protecting device, against under-voltage, over-voltage, over-flow, overload, waterless, etc; Also with an automatic switch and water level sensor that can on/off the pump when the well is dry and the water tank is fully.
2. Pump head: 10-300m, Flow rate: 1.8-60M3/h.
3. Working temperature: -5-50degree
Service life:
Solar panel: 20-25years;
Pump comtroller: 10years
Water pump: 30, 000hours. Â
