When you do a leaching test, how is segmented cleaning done? What is the general consumption volume ratio?
Is it a small trial or an expanded trial? It depends on how you think about it. If the requirements are higher, you can add a certain amount of water to the filter cake and stir it before filtering, or add water directly and vacuum filter.
It is still in the small trial stage, but I feel that the cleaning volume is too large, the leachate is diluted, the circulation cannot go back, and the circuit cannot be opened after cleaning.
Gui and lotion liquids are separated, and Gui liquid is used for cyclic leaching. Only in this way does cyclic leaching make sense?
Low-concentration lotion can be used for leaching raw ore, and the volume ratio is determined according to your actual situation.
After one leaching, solid-liquid separation is carried out. The separated slag is slurried according to the original leaching solid-liquid ratio, and then solid-liquid separation is performed again, and the slag continues to be slurried, and so on. Generally, it is enough to wash with water three times. The water system is that the water from three washes is returned to the second wash, the water from the second wash is returned to the first wash, and the water in the first wash is returned to leaching.
