Effect of phosphate quality on foam generation during the phosphoric acid production process

The presence of organics materials in phosphate ores generates foam during the manufacture phosphoric acid, thus affecting production performance and quality products. Today, industry defoamers are used to reduce negative impact production. In present work, we focused on root cause evaluation for generation acid process, evaluated effect rock terms organic carbon (OC) carbonate content, using a laboratory protocol foaming ability evaluation. results show that there is relationship between volume generated values those impurities, while higher when concentration OC Carbonate high. our confirm can be avoided if less than 0.1% 3% carbonate.
