OLIVINE/ DUNITE FOR INDUSTRIAL AND

The olivine process which has been invented to neutralize industrial waste acids with olivine is an environmentally and economically attractive procedure. The process can be further developed as new industrial method to produce precipitated silica, synthetic clays, synthetic zeolites and/or high purity magnesium-sulphate products.

Dunite ( Olivine Sand ) Dunite, the parent rock of Magnesite contains 38-42% of MgO and 39% of SiO2 and the Magnesite is derived from the Dunite. It is dark Grey to Olive Green in colour. USAGES. In Refractory Industries to manufacture Dunite Refractory Bricks. Used

Olivinedunite - Olivine Manufacturing, Trading,

In industry, olivine is used to produce heat-resistant glass and refractory materials. This mineral is also used for the production of iron ore pellets and as a catalyst in wood gasification processes. Thanks to its high heat storage capacity, olivine also increases the power-to-weight ratio in lithium-ion batteries and is suitable for night ...

Dunite / Olievin Sand - Karnataka silicates

DUNITE / OLIEVIN SAND. Dunite is an igneous, plutonic rock, of ultramafic composition, with coarse-grained or phaneritic texture. The mineral assemblage is greater than 90% olivine, with minor amounts of other minerals such as pyroxene, chromite and pyrope. Dunite is the olivine-rich end-member of the peridotite group of mantle-derived rocks.

Olivine greenSand

Olivine is a common volcanic mineral that can be found in large quantities all over the world. The unique feature about greenSand olivine products is the ability to clean up CO2 as nature has done for billions of years within the results of negative emissions. In nature, this process takes place with minerals like Olivine that work as CO2 removal.

About Olivine - Olivine is a Natural Mineral.

The manufacture of Olivine sand involves crushing, grinding and screening with a strict control on these processes. The chemical composition and sieve analysis have been found to be very consistent from time to time. Inorder to benefit from the advantages of Olivine Sand further, reclaiming of

Green Sand Olivine - GreenSand

How does Olivine. Olivine is a common mineral in dunite rock that clears up CO₂ in the soil, air and water. The weathering process is a 'slow release process'. CO₂ reacts with olivine and water. The newly created substances are sand, magnesium and the bicarbonate (= lime) in which the CO₂ is included.
