Embodiment Construction
[0012] The specific implementation manner of the present invention will be further described below in conjunction with the accompanying drawings.
[0013] Such as figure 1 Shown, a kind of iron ore concentrate concentration dehydration processing novel process is characterized in that comprising the following steps:
[0014] a Feed the iron ore concentrate slurry with a concentration of 55%-70% into the mixing tank for stirring;
[0015] b After being stirred by the mixing tank, the iron ore concentrate slurry is fed into the filter for dehydration through the underflow pump;
[0016] c The iron concentrate filter cake with a water content of 8.5%-9.5% dehydrated by the filter is used as the final product, and the filtrate with a concentration of 0.3%-0.5% is imported into the filtrate pump pool, and enters the water treatment system of the mineral processing plant for recycling, while The overflow of the filter with a concentration of 45%-65% returns to the mixing tank to f...
