Opal is made of silica, but it technically is not a mineral.
Diatoms are the phytoplankton with a glass-like shell made of silica. These minute algae have cell walls called frustules that are made of opaline silica, which gives them a distinctive glassy appearance. Diatoms are important primary producers in aquatic ecosystems and play a significant role in the food web.
Any metrial or thing which containts silica in it is call silica content..
Rhyolite is silica-rich, containing over 70% silica. It is an extrusive igneous rock with a fine-grained texture that forms from the rapid cooling of magma rich in silica content.
Krakatoa is silica-rich, meaning it contains a high amount of silicon dioxide (silica) in its composition. This high silica content is associated with explosive volcanic eruptions due to the interaction between silica and magma.
Solute silica refers to dissolved silica present in a solution, typically in water. It represents the amount of silica that has been dissolved and is in the liquid phase rather than in solid form. Silica can be found naturally in many water sources and can impact water quality and the environment.
Geyserite is a type of siliceous sinter, a form of opaline silica that is deposited around geysers and hot springs. It forms when hot water dissolves silica underground and then brings it to the surface where it precipitates out as the water cools, creating a characteristic white to gray mineral deposit. Geyserite can often be found encrusting the edges of geyser basins and pools.

Opaline fallow refers to the birds that are usually sold in the Philippines. They are usually yellow, orange and blue in color.

There is no scientific name per se for a rice hull.However, according to Wikipedia:"To protect the seed during the growing season, the hull is made of hard materials, including opaline silica and lignin.... The very high content in amorphous silica of the hulls confer to them and to their ash (SiO2 ~ 20 wt.%) after combustion very valuable properties."

where can silica mineral can be found
Yes. Silica is everywhere.
The chemical compound silica is an oxide of silicon .In other words; silicon is in silica.
Calcite does not contain any silica. It is a carbonate mineral.
