Lunar resources

The Moon bears substantial natural resources which could be exploited in the future. Potential lunar resources may encompass processable materials such as volatiles and minerals, along with geologic structures such as lava tubes that together, might enable lunar habitation.The use of resources on the Moon may provide a means of reducing the cost and risk of lunar exploration and beyond.

Leaching Mechanism of Cr(VI) from Chromite Ore Processing

The leaching behavior of hexavalent chromium (Cr(VI)) and major metal elements relevant to Cr(VI) leaching from chromite ore processing residue (COPR) to HNO3 are investigated by batch leaching tests. According to the test results, aqueous Cr(VI) accounted for 70 80% of the content of total Cr. Cr(VI) concentration was controlled by the dissolution degree of Cr(VI) bearing minerals (such as
