How to achieve scientific mineral allocation
Thread Content
Since our company has no minerals, we purchase and use minerals from various mineral producing areas across the country. It is very important in terms of ore distribution and use. We also attach great importance to this aspect of work, and have also taken related tasks such as analyzing the slurry content every day. However, due to many reasons, we feel that the effect is not ideal. Management should be a direction for us to strengthen. At the same time, we would also like to hear the opinions of our peers.
The key to ore blending lies in the uniformity and stability of the ore blending. Similar ores (based on origin and composition) are grouped into one category to avoid too many types. In this way, various ores are divided into 2 to 4 categories, or more. After crushing, they are stored in different storage tanks, and the ingredients are batched using electronic scales (the ratio is selected according to the content properties) for pulping. To achieve stability and uniformity.
In fact, the actual ore blending is determined based on the actual production. Sometimes the quality of the ore slurry you measure is okay, but the reaction is not necessarily good. The reverse reaction process in the wet phosphoric acid production reaction tank is complicated. You can try to combine it with the actual production to determine the ore blending plan.
Reply 1# panyongyuan It is best to mix ores of different qualities and tastes according to the quality of phosphate rock (impurity content) and phosphoric acid taste (content of phosphorus pentoxide), so as to ensure the normal operation of production when the quality of phosphate rock is different.
