Silica sand is an emerging project for NZIMMR, with a view on improving the price point for mined and processed silica sand in New Zealand. Prices globally vary from $50 per tonne to $5,000/t, depending on product quality and applications. The starting point for New Zealand resources is more likely to be in the realm of $100-150/t.

2017-2-9 Amorphous silica is deposited by hot springs as silica sinterand by hydrothermal alteration of nearby rocks involcanically active areas. In the Taupo Volcanic Zone,acid sulphate alteration in the near surface parts of activegeothermal systems has resulted in the conversion of allminerals, except primary quartz, to an assemblage ofamorphous silica + cristobolite ± native sulphur, alunite,cinnabar and barite (Roberts, 1997). The end result is alow density, white, porous rock composed primarily ofamorphous silica and residual quartz phenocrysts. Threeamorphous silica deposits have been explored recently,Tikitere and Taheke, near Rotorua, and Lake Rotokaua,near Taupo (Fig. 2). The Tikitere deposit is currently beingmined by Microsilica New Zealand

At Sibelco, we produce the crystalline forms of silica – quartz and cristobalite – as both sands and flours. Silica is hard, chemically inert and has a high melting point, making it a valuable material in a range of applications and industries, including paints plastics, ceramics, glass, filtration and agriculture.

2021-5-30 This has eventuated because of the nature of the ore mined locally and used in the process. Early pioneering experiments failed to successfully smelt iron from New Zealand's west coast ironsand deposits because the magnetite ore (Fe 3 O 4), as it is known, is locked in with minerals such as titania and silica. These bonded oxide impurities are ...

2018-6-27 In New Zealand, natural amorphous silica deposits in the Rotorua district have been commercialised. These deposits are hosted in hydrothermally altered rhyolitic rocks –Mamuka Ignimbrites and Rotoiti Breccia – estimated to be 60,000 to 200,000 years old. The deposits have been extensively altered geologically, with widespread silification17 ...
