    <p num="0001">&lt;p&gt;The present invention provides process and equipment for producing potassium chloride using carnallite as the t.eedstock. The process of the present application comprises the following steps: crushing, rvashing, urinding, crystallizing, and direct flotation. In the present invention, by optimizing thc proccss paramctcrs and the process flow, industrial million-ton scale continuous production of potassium chloride fi&amp;#39;om camallite is achieved with high production effrciency, and significantly improvcd quality of the potassium chloride product, such as purity, whiteness, and crystal grain size.&lt;/p&gt;</p>
