wholesale chanel jewelry replica 1. Use water to spread it, like Taomi! Washing sand gold!
2. It can also be poured into mercury and then filtered the sand, and then heated mercury, but this method is prone to mercury poisoning;
3. Use potassium hydroxide

During the crushing and screening stage, many sand gold mines contain glue mud balls, and their particle size is greater than 100 mm. If this mud ball is not broken, it will be discharged with the waste stone during the screening process, causing gold losses. In addition, vibration sieve and drum screens are often used as screening equipment. The two have long service life and have a large processing ability.nCompared with the method of mineral procurement methods, such as gold ore flotation method, cyanide immersion method, etc., the method of extracting gold in sand gold ore is much simpler. That is the re -election method. The commonly used re -selection equipment includes spiral grooves, sawtooth wave jumping machines, shake beds, etc. This method is not only simple and efficient, but also uses the physical properties between minerals, so it is very environmentally friendly and the cost is low. It is better to extract gold from the sand!n3. The two -step preparation work in the selection phase will be officially entered into the selection stage. At this stage, the separation of gold and sand will be completed. Practice has proved that the re -election method is the effective and economic treatment method of Sandin Mine. Due to the different particle size composition of gold in the gold ore, the effective granularity boundaries of different sand mineral mining equipment on the processing materials are also different. Therefore, the reasonable sand gold selection process should be jointly assigned by several different re -selection equipment.nGenerally, the church crusher is mostly crushed with jaw crusher, and the crusher is used in cone crusher. The choice of vibration sieve and roller screen lies in different occasions. If the river sand is dug out, and the screen is sieved, the vibration screen is selected; if the gold ship is operated on the water, the drum screen is generally selected. 2. During the mud -deduction stage, a lot of mud will be mixed in. If the mud treatment is not performed in advance, it will cause a great burden on the subsequent election phase, and will also increase the selection workload, causing unnecessary economic losses. In the muddy stage of the sand gold, the muddy bucket of various specifications is generally used to complete the work, removing the mud mixed in the sand gold.nBe careful to check it ~ Please help me like it ~ Thank you, I wish you a happy life!n4 morenBleak
