Introduction to the report:

Foreword
Entrusted by Shandong XXX, Xi'an Tianzhou Mining Technology Development Co., Ltd. conducted preliminary research on the vanadium-bearing ore in a certain area from the end of June to the beginning of July 2007. Discussion of experimental research including raw ore sample screening, test sample preparation, multi-element analysis, flotation enrichment and roasting leaching.
According to the experimental study, the results are as follows:
(1) Raw ore (-2mm) - (+0.25mm) The coarse grade contains V 2 O 5 is lower, and the (-0.098mm) fine grade contains V 2 O 5 higher.
(2) The ore contains V 2 O 5 0.58%, and the grade of V 2 O 5 can be increased by flotation. When the crude concentrate is enriched to a double V 2 O 5 grade of 1.25%, the recovery rate is 84.66%; when the concentrate grade is enriched to the original ore, the grade of V 2 O 5 is 1.81%, V 2 O 5 The recovery rate was 70.89%.
After the ore was enriched by flotation, we conducted a preliminary investigation on the extraction of V 2 O 5 by roasting and leaching. The test results are:
1 The direct blasting rate of V 2 O 5 of the original ore is 60%;
2 The leaching rate of calcification roasting V 2 O 5 was 70%.

According to the investigation, the following preliminary conclusions can be drawn: the vanadium ore can be enriched by flotation, and the leaching rate of V 2 O 5 by calcification roasting (environmental “cleaning method for vanadium extraction”) is 70%. This test is a simple discussion of the test, the specific feasibility and the best indicators need to pass the system test and research before final confirmation.

Exploring experimental research conclusions

After preliminary exploration and experimental research, the vanadium ore in this area can be considered for direct grading of raw ore or roasting and leaching after flotation and enrichment. It is recommended to take representative ore samples again and further study the system.
