Embodiment Construction
[0016] The specific embodiment of the present invention is further described below in conjunction with accompanying drawing:
[0017] Such as figure 1 with figure 2 As shown, the selective flocculation and separation process of microfine coking coal of the present invention has the following steps: it utilizes a mixing tank to be composed of five parts: strong stirring, gentle stirring, strong stirring again, gentle stirring again and flotation. Stirring refers to high-speed stirring; described mild stirring refers to low-speed stirring;
[0018] a. First, feed the fine-grained coal slime 1, flocculant 2, and dispersant 3 produced after coking medium coal or flotation tailing coal grinding into the mixing tank A for 2 minutes of strong stirring, so that the pulp is fully mixed under high-intensity stirring. dispersion;
[0019] b. Feed the fully dispersed ore pulp 4 after strong stirring into the mixing tank B and then gently stir for 2 minutes. In a mild environment, the ...
