Abstract
The secondary diatomite of Changbai Mountain of Jilin province contains about 20% mineral impurities, can not be directly used for processing high-end products, secondary soil is purified to the indexes of primary soil, and high-additional-value products such as a filter aid and the like can be processed. In the invention, a water-separation method is adopted for purifying, impurities and diatom shells are separated by water separation (twice scrubbing), and the impurities are separated and removed, so that the diatomite is purified and reaches the indexes of primary soil. A source of primary soil is added, excessive exploitation of primary soil is reduced, and the exploitation life of mines is prolonged, so that the method is beneficial to sustainable development of the diatomite. The method has the advantages that acid is not needed for treatment, no heating is needed, so that no waste acid liquid is generated, also the energy is saved, the production cost is low and no environmental pollution is caused.
Description
The present invention is the Purification of Diatomite method, belongs to ore-dressing technique.
The purifying technique process, diatomite is pulled an oar (Gu: liquid=1: 3.5～4,120 rev/mins, stirred 30 minutes), clean then (Gu: liquid=1: 8～10,800～100 rev/mins, stirred 30 minutes), detrital mineral was removed in sedimentation in 3～4 minutes, and sedimentation made diatomite and suspended clay mud separation in 4～5 hours again, carry out secondary by aforesaid operations and remove detrital mineral and suspended clay mud, the diatomite-oven dry-pulverizing that obtains purifying (200 order)-packing-warehouse-in.See accompanying drawing 1.
Present method is purified and to be different from acid treatment, does not heat, technology is simple, production cost is low.Also reusable edible (making beating, scouring) of water is deviate from recyclable utilization after the suspended clay sedimentation, and detrital mineral (thick slag) belongs to sand, can fill out hole, pad road, and no waste water, waste residue are free from environmental pollution.
Secondary Purification of Diatomite experimental result (%)
Present method purification is the result show, secondary soil can refer to pure to one-level soil index.Average yield 64.10%, middle native average yield 11.3%, adding up to total yield is 75.40%.

Claims (5)
1. washing is soaked diatomite 4-6 hour before purifying, and pulls an oar, cleans purification then.
2. clean purification process and need powerful the stirring, break away from from diatom test in order to impurity, stirring arm is answered spin under the tool, avoids the mud outflow.
3. sedimentation is removed heavy detrital mineral impurity and sedimentation diatomite should carry out in the synthetic glass cylindrical pressure vessel.To handle 1 kilogram of diatomite is example, and tube is high about 40 centimetres, 22 centimetres of tube end diameters, about 15 liters of capacity.Because of synthetic glass is transparent, in order to observing the separate and subside situation.
4. grasp the settlement separate time, the settlement separate detrital mineral time will lack, because of its than great, sedimentation is fast.And the sedimentation diatomite time will be grown, because of it has certain suspension, especially wherein fine particle.
5. when clean purifying, with sodium hydroxide and Sodium hexametaphosphate 99 accent mud PH9-10, to guarantee its dispersiveness.
