The stunt of China Platinum

Color judgment method. The "color judgment method" invented by Pan Congming has become the most representative stunt and stunt of platinum group metal refiners in China, and the "green and efficient extraction technology of platinum, palladium, rhodium and iridium from nickel anode slime" created by Pan Congming has broken through the technical bottleneck of long process flow, low resource utilization rate and poor adaptability to complex raw materials. Many people will think that platinum and silver are somewhat similar, but they are not the same texture. Platinum is silvery white or grayish white, between the colors of silver and nickel, and its texture is fine and smooth.
