Bismuth is a diamagnetic element, which means that it naturally repels both the north and south poles of magnets equally, and when combined with a strong neodymium magnet at the top of the sculpture, the central magnet cube between the crystals will more or less float there forever.

Bismuth, a brittle, silvery-white, less toxic metal placed after the transition elements in the periodic table. It has a low melting point and thermal conductivity. It gets easily oxidized in air. It is naturally available in the form of bismuth oxides and bismuth sulfides with outstanding electronic and optical properties.

The leach recovery of bismuth was calculated using the analysis of the bismuth glance flotation concentrate and the leach residue and its mass. Thereinto, sodium chlorate was used as oxidization agent and lignin calcium was used to selectively enwrap the other sulfide excepted bismuth sulfide. Bi2S3 + NaClO3 + 6HCl = 2BiCl3 + NaCl + 3H2O + 3S

Get priceBismuth (Bi) is a silvery-white metallic element with a pinkish tint on freshly-broken surfaces. The most common bismuth minerals are bismuthinite and bismite, but most bismuth is recovered as a by-product from lead processing. Relation to Mining Most bismuth is produced from mines in China, Mexico and Bolivia.

Hydrogen peroxide (H2O2) is a strong oxidizer that causes non-selective oxidation of sulfide minerals, and its influence on bismuth sulfide ores is not well-documented. In this study, H2O2 was proposed as an alternative bismuthinite depressant, and its effect on a Mo-Bi-containing ore was intensively investigated by batch flotation tests. Results showed that the addition of H2O2 significantly ...

For the angler, the Bi-Visible is both "Visible" on the water and if tied with quality dry fly hackle is a high floater that retains its flotation properties well.
