Mixing speed, time of repose and gas injection speed etc. are had studied to the shadow of tin-lead soldering performance by following test method
It rings.
(1) mixing speed (as shown in Figure 1)
In the case where other conditions are consistent, the speed of rotation has apparent influence to the tin-lead soldering effect of product, with
The continuous quickening of the speed of rotation, product flotation efficiency is presented first increase after reduction trend, and with the later period speed of rotation
Quickening, the reduction trend of product suspending efficiency is getting faster.Wherein, when rotation speed is lower than 3500r/min, product is floated
Efficiency is selected to gradually increase with the quickening fiber number of the speed of rotation, and when revolving speed reaches 3550r/min, flotation efficiency highest,
When the speed of rotation is in 3600-3800r/min, the flotation efficiency of product is being gradually decreased with the quickening fiber number of heating rate,
It is reduced to 85% by 98%, when the speed of rotation is greater than 3600r/min, the flotation efficiency of product is fine with the quickening of the speed of rotation
Degree is being reduced rapidly.
(2) time of repose (as shown in Figure 2)
Time of repose refer to by completely stir after product again at a certain temperature carry out constant temperature standing, be in order to
Impurity in textile raw material is further discharged by standing.As seen from Figure 2, flotation efficiency is with time of repose
Extension and reduce.When being lower than 3 hours between upon standing, flotation efficiency, average flotation efficiency is 96%, therefore is had good
Flotation efficiency, upon standing between when extending to 3.5 hours, flotation efficiency is substantially reduced, and average flotation efficiency is 85%, works as standing
When time is greater than 4 hours, flotation efficiency is extremely low, average pore 80%, this is for tin-lead soldering, and flotation efficiency is
It is extremely low.
This is because cassiterite is also gradually precipitating with the extension of time of repose, the content of cassiterite is caused also gradually to drop
It is low.
(3) gas injection speed (as shown in Figure 3)
As seen from Figure 3, the flotation efficiency of product is reduced with the extension of gas injection speed.When gas injection speed is lower than
When 50L/min, the flotation efficiency of product is higher, average pore 96%, therefore has good flotation efficiency, when gas injection speed
When degree extends to 55L/min, flotation efficiency is substantially reduced, and average flotation efficiency is 85%, when gas injection speed is greater than 60 hours,
The flotation efficiency of product is extremely low, average pore 80%, and for tin-lead soldering, porosity has been extremely low for this.
Based on above-mentioned, it is an advantage of the current invention that the present invention is directly using cassiterite as raw material, in order to guarantee effectively returning for cassiterite
It receives, the mistake of cassiterite should be avoided to crush as far as possible in ore grinding and carries out multiple the second-order separation and screening, substantially increase same particle size
The accumulation rate of cassiterite improves pretreated first enrichment, and during carrying out collecting, utilizes stirring, standing and sky
Air bearing choosing, greatly reduces the flow time of process, improves the service efficiency of actual production, and can also carry out secondary point
Classification processing is carried out after choosing and respectively obtains cassiterite and recovered liquid, is improved the thick recovery utilization rate of drug, is reduced production cost.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
