What is the cause of excessive or too small ore concentration? How to adjust?

Check the mine record first to see if there is any change in the mine volume. If it increases, if there is no other reason, the mine amount can be adjusted. Or check whether the water pressure changes, such as low water pressure (realized to reduce water flow) caused by excessive concentration, should also reduce the amount of minerals to adapt to changes. If the amount of water can be effective at this time, the amount of water can also be adjusted to adjust the concentration. If the concentration is less than the specified requirement, the adjustment method is the opposite of the method of excessive concentration. It should be noted that in the adjustment process, it is necessary to pay attention to the changes in other operating conditions to prevent this from happening.
