Iron beneficiation process for potassium feldspar, comprising: a crusher with feldspar, crushed materials into the drum sieve, particle size of 6 mm particles into the mill to a fine powder, which It is characterized in that it also includes the following process steps. A. Washing the mud: send 20-200 mesh fine powder materials into the spiral chute, separate and sort, and select the sediment; B. Sorting: The material that has been removed after the sorting is sent to the shaker to wash out the ferric oxide; C. Selection: The material from which the ferric oxide is removed is sent to the 1024-type strong magnetic re-election machine for selection, and the iron and mica materials are selected, and then the material is sent to the 1018×2 type magnetic separator, and the material is selected again. Iron and mica substances; D. Purification: The materials that have been re-selected and universally selected are sent to the high-frequency vibrating screen for screening, and the ferric oxide and triiron tetroxide in the powder are removed to obtain the potassium feldspar fine powder; E, pickling powder: using sulfuric acid as the pickling agent, according to the acid concentration and the iron content of the potassium feldspar fine powder, in the case of determining the sulfuric acid concentration, the iron content of the potassium feldspar fine powder The weight of the added sulfuric acid is proportional to the weight, and the iron oxide and the ferric oxide are completely removed by pickling, and the ferrous sulfate solution is separated to obtain the potassium feldspar fine powder; F. Screening potassium feldspar fine powder: The potassium feldspar fine powder is sent to a 20-200 mesh sieve, and the sieved product is a finished product having an iron content of less than 0.24%. This sifter machines are applicable to grade of dry powder granules materials in pharmaceutics, chemical industry, foodstuff industry, etc. The screening machine consists of the vertical vibrating motor, a sieve bottom, a mesh frame, screening room, the rubber vibrating bowl. This machine can be used for single layer or multiple layers grading.Compact structure, convenient operations and maintenances, stable running, low noise, large quantities of materials-treating, good fineness, strong applicability, etc. Sifter Machine,Screening Machine,Sieving Machine,Vibrating Screener JIANGYIN CITY XUAN TENG MACHINERY EQUIPMENT CO.,LTD , https://www.xuantengmixer.com
