Vanadium. Large amounts of vanadium ions are found in a few organisms, possibly as a toxin. The oxide and some other salts of vanadium have moderate toxicity. Particularly in the ocean, vanadium is used by some life forms as an active center of enzymes, such as the vanadium bromoperoxidase of some ocean algae .

In nature, silver is often associated with other metals and, in fact, much of the silver that makes its way into the world market is coproduced as a byproduct of the mining processes for other metals like copper, zinc, and lead. Most silver is mined in Mexico, Peru, Canada, Australia, and the United States.

Rhenium has one of the highest melting points of all elements, exceeded only by tungsten and carbon. It is also one of the most dense, exceeded only by platinum, iridium, and osmium. Rhenium's usual commercial form is a powder, but this element can be consolidated by pressing and resistancesintering in a vacuum or hydrogen atmosphere.

Rhenium Wikipedia. Rhenium in the form of rheniumplatinum alloy is used as catalyst for catalytic reforming, which is a chemical process to convert petroleum refinery naphthas with low octane ratings into highoctane liquid products. Worldwide, 30% of catalysts used for this process contain rhenium.
