Embodiment Construction
[0013] Clay-type gold ore heap leaching mineral processing technology, it is realized by the following steps:
[0014] 1) Raw ore crushing: Clay type (later type or black soil type) gold ore is crushed, the particle size is <5cm, and the optimum value is <3cm.
[0015] 2) Agglomeration: ①Put the chaff and broken clay-type gold ore into the granulator and mix them evenly. The dosage should be 2-5kg per ton of ore, and the clay should be more than the gravel Take the larger value when the clay is less than the gravel; ②Add enough water when granulating, the amount of water added is 15-25% of the weight of the dry material, intuitively, the pellets are not seriously sticking to the belt.
[0016] 3) Heaping: During the heaping process, the aggregates should be piled up in sections before drying, and immediately covered with a layer of straw to keep the aggregates moist. In order to achieve uniform distribution of liquid, the straw should be short and the length is About 20cm.
