Many people are interested in the production method of iron oxide red. It is necessary to know that there are many production methods of products, but no matter which one is, the quality of the product must be guaranteed. Zibo Shuangmu pigment has summarized a relatively reliable production method based on years of production experience is the ammonia-alkali production method. Now let us understand the ammonia-alkali production method of iron oxide red.

1. The iron ore concentrate crushed to a fineness of 120 was sent to the reaction kettle, and 2T hydrochloric acid, 0.2T nitric acid, and 0.1T boric acid were added to allow it to react in the reaction kettle for 4 hours.

2. Pump the solution in the reaction kettle to a neutralization tank with a stirrer, start the stirrer to slowly add ammonia water and NaOH solution, and simultaneously drive the neutralization tank with a pump after being cooled by steam.

3. Squeeze the extracted turbid liquid, put the solid matter left in the filter into a dryer, and then put it into a baking tray. The finished product is iron oxide red and can be used for pigments.

The production of iron oxide red using the ammonia-alkali method is a relatively fast and simple method, and the iron oxide red products produced by this method are relatively high in purity and the materials used will not be much. It can be said that it is a new type Production method. If you want to know more about the product of iron oxide red, you must remember to pay attention to our website update.
