Show as a result: the acid liquid has good temperature-tolerance performance; it also can reduce the filtration efficiently and delay acid - rock reaction speed.

结果表明：研制的酸液体系具有良好的抗温性能，可有效地降低酸液滤失和延缓酸-岩反应速度。

Phosphate rock (plasma) and sulfuric acid reaction, the reaction slurry to liquid-solid separation, dilute phosphoric acid to be wet.

磷矿粉(浆)与硫酸反应，反应料浆进行液固分离，得到湿法稀磷酸。

The acid decomposition reaction of phosphate rock is not the exchange between ions, but the exchange between functional groups.

磷矿酸解反应并非是离子间的交换，而是功能基团之间的交换。

Mr. TOM McCOLLOM (Geochemist, University of Colorado): The sulfate salts that are in there come from reaction of the rock with sulfuric acid rather than from evaporation of a fluid.
