Vanadium resources in China have the following characterisitcs:

1) Widespread resources and relatively concentrated reserves.

Vanadium resources are widely distributed in 20 provinces, autonomous regions or municipalities and relatively amassed in Sichuan, Hunan, Anhui, Guangxi, Hubei and Gansu. Deposit types are chiefly magmatic (V-Ti-magnetite deposits) and sedimentary (deposits in black sequence).

2) Low-grade ores and by-product vanadium.

The vanadium is all recovered as a by-product and the ores are all low in grade. In the Panzhihua-Xichang region the grades range from 0.11%~0.44% vanadium, averaging 0.24% (Table 3.6.3); in the black sequence the highest grade is 4.79% and the lowest about 0.3%, averaging about 1%; and of the volcanic-type deposits the grades are generally about 0.20%. Over 92% of the vanadium reserves in China occur in coexisting or associated deposits and, thus, all the vanadium produced in the country is a by-product recovered from ores of other minerals.

3) Monotonous industrial type of deposit.

The majority of the vanadium deposits presently mined and used in China are genetically of magmatic and sedimentary types, a few of other genetic types, and no placer vanadium has so far been discovered. Besides occurring in black sequence, sedimentary vanadium may coexist with uranium and phosphorus in sandstones, mudstones and their metamorphic series.

4) Deposits are generally large in size; large and medium-sized deposits are many.It can be seen from Table 3.6.2 that the reserves of 10 large deposits (each containing more than 1 million tons of V2O5) make up 46.7% of the total and those of the medium-sized deposits (each carrying 0.1~1 million tons of V2O5) constitute 47.66% of the total. The two add up to more than 94% of the total.

5) Low-degree prospecting and small industrial reserves.The reserves obtained in the prospecting stage account for only 45.5% of the total, while those obtained in the stages of reconnaissance survey and detailed investigation amount to 54.5%. In addition, the industrial reserves form only 36.6% of the total.

Henan Hongxing Mining Machinery Co., Ltd is a joint-stock mining machinery manufacturing enterprise integrated in scientific research, production and marketing.
