The process of reusing the treated water generated during this process and that of recovery of molybdenum from the excessive water were studied.
The results were as follows.
Molybdenum recollection
1. Reusing processing water generated after dissolving process on FL/20 type, the following were the remaining Mo.'s weights after the 1st, 2nd, 3rd, 4th, 5th, & 6th dissolutions respectively.
1) The result of measuring the quantity of Mo. in processing water(the 1st solving water) generated after the 1st dissolving Mo. process was 369g/ℓ
2) The result of measuring the quantity of Mo. in processing water(the 2nd solving water) generated after the 1st dissolving Mo. process reusing the 1st solving water was 627.3g/ℓ
3) The result of measuring the quantity of Mo. in processing water(the 3rd solving water) generated after the dissolving Mo. process reusing the 2nd solving water was 808.11g/ℓ
4) The result of measuring the quantity of Mo. in processing water(the 4th solving water) generated after the dissolving Mo. process reusing the 3rd solving water was 934.68g/ℓ
5) The result of measuring the quantity of Mo. in processing water(the 5th solving water) generated after the dissolving Mo. process reusing the 4th solving water was 1023.27g/ℓ
6) The result of measuring the quantity of Mo. in processing water(the 6th solving water) generated after the dissolving Mo. process reusing the 5th solving water was l085.29g/ℓ
2. The followings were the results of recollectings Mo. in processing water respectively generated after dissolving Mo. to produce complete goods df FL/20 type filament.
1) the percentage of recollecting Mo. in the 1st solving water was 93.0%
2) the percentage of recollecting Mo. in the 2nd solving water was 94.5%
3) the percentage of recollecting Mo. in the 3rd solving water was 95.5%
4) the percentage of recollecting Mo. in the 4th solving water was 96.0%
5) the percentage of recollecting Mo. in the 5th solving water was 96.2%
6) the percentage of recollecting Mo. in the 6th solving water was 96.4%
3. The followings were the results of analyzing, with ICP, holding quantities of Mo. in the 6 processing waters to produce FL/20 type filament after passing a 3 staged solid-liquid separator through, dehydrating and drying for more than 3 hours in a dryer to recollect solving Mo. in them.
1) the Mo. holding percentage in the 1st solving water was 76.6%
2) the Mo. holding percentage in the 2nd solving water was 76.6%
3) the Mo. holding percentage in the 3rd solving water was 76.6%
4) the Mo. holding percentage in the 4th solving water was 76.6%
5) the Mo. holding percentage in the 5th solving water was 76.6%
6) the Mo. holding percentage in the 6th solving water was 76.6%
It was noted that with the number of times the recollecting Mo. percentage become higher, and in spite of much recollecting, without any large effect on the goods the solving water could be reused as the processing water. Because the collected Mo. holding percentages were more than 76%, it is considered they are very good one than Chinese Mo. ores with 50% degrees of purity, worthy of recollecting Mo.
The results were as follows.
