首先，将石灰与水混合，反应十分激烈，操作时要小心！将粉末倒入水中，别搞反了。这样更容易控制反应的速率。
First hydrate the lime, taking care, for the reaction is violent! Pouring the powder into the water, and not the contrary, makes it easier to control the rate.
氧化控速过程为“界面反应和扩散混合控制过程”。
The oxidation control factor is "the mixed control of interface reaction and diffusion".
浸出过程属于混合控制，即表面化学反应与通过不溶硅、铁矿物相的扩散为过程的控制步骤。
The leaching process is controlled by mixed steps:the surface chemical reaction and the diffusion passing through the silicon and iron mineral phases.
