How is silica mined?
The technique for silica mining depends on the location of the silica. Sand, the most common and readily available source of silica is found in beach and basin deposits, large dunes in desert areas, underground in glacially deposited pockets, and in sandstones. In most deposits the removal is done by surface mining, with the aid of large earth moving equipment, transported by conveyor or mining truck to a central location, and distributed via truck to purchasers.
What is Reactive Silica?
Dear Sirs/madumHow to remove silica from R O Plant feed water.Kindly advice.Regards Arunoli
What is the best way to clean of remove deposits from a copper penny?
The deposits on the surface of the coin were part of the coin body. Removing these deposits is removing part of the coin. A coin collector will not do this.
How can a basalt flow cause opal to form?
If the basalt flow contains air bubbles and pockets and there is a spring that contains silica then the silica can deposit into the air bubbles (the air bubbles are known as Amygdaloidal basalt or vesicles) If the silica deposits slowly and the conditions are correct then precious opal can form. Two examples of this would be in California at the Nowak and the Barnett mines.
How do you dissolve sand in a block storm water pipe?
Sand cannot be dissolved because it is a form of silica and there is no solvent for it. You will have to mechanically break through the sand and then flush the particles a away with significant amounts of water.Snaking (rodidng ) normally is not used to scour a line or remove mineral deposits. In some cases a "chain knocker" is used but if the piping is in questionable condition then any defects will appearThe ideal way to remove scale and mineral deposits is the use of a water Jetter as the high pressure stream scours the line the volume of watter will help flush it away
Is deoxidizer the same as silica gel packs?
No. Silica Gel packs remove moisture. Deoxidizer packs remove oxygen.
What is the effect of silica on steam turbine blades?
Although several factors influence the formation of deposits on turbine components, the general effect is the same no matter what the cause. Adherent deposits form in the steam passage, distorting the original shape of turbine nozzles and blades. These deposits, often rough or uneven at the surface, increase resistance to the flow of steam. Distortion of steam passages alters steam velocities and pressure drops, reducing the capacity and efficiency of the turbine. Where conditions are severe, deposits can cause excessive rotor thrust. Uneven deposition can unbalance the turbine rotor, causing vibration problems.The nature of silica deposits found on turbine blades varies greatly. lists a number of silica compounds that have been identified in various studies of turbine blade deposition. Of these, amorphous silica (SiO2) is the most prevalent.Localized Silica Saturation. Turbine deposits are also formed where localized silica saturation occurs and silica condenses from the steam in those areas of the turbine. Partial evaporation of the precipitated silica can then occur with only a portion of the silica being dissolved by the continuous steam flow. Deposits remain as a result.Turbine Velocity. Another factor affecting the location of turbine deposits is the velocity in the turbine. Steam flows from the inlet to the outlet of the turbine in only a fraction of a second. Consequently, deposition is shifted downstream from the saturation point by the high steam velocities.Prevention of Silica DepositsThe most significant factor in minimizing turbine silica deposits is the maintenance of low silica concentrations in the boiler water. External treatment equipment must be operated carefully to limit the amount of silica entering with the makeup water, and the condensate must be monitored to minimize contamination. After silica enters the boiler water, the usual corrective action is to increase boiler blowdown (to decrease the boiler water silica to acceptable levels) and then to correct the condition that caused the silica contamination.
Where is silica?
Silica is the mineral quartz (SiO2) and silicon is the element (Si) which is a major rock forming element in Earth's crust, and is therefore found nearly everywhere. Concentrations of silica which are mined are usually in the form of quartz sand or sandstone deposits.

You can remove mineral deposits from your teapot with a mild vinegar solution.

Stalactites and stalagmites consist of deposits of?
silica. +++ Wrong. They are of the mineral Calcite: crystalline calcium carbonate derived from the limestone above the cave.

The sand used in industrial applications is mined from silica sand and sandstone deposits in 35 states.

What is the function of a silica gel in a circuit?
Property of Silica gel is to absorb the moisture. Colour of dry silica gel is blue and it turns into pink when it is saturated with moisture. When the colour of silica gel turns out pink, the wet silica gel is removed and the fresh silica gel is filled. The wet silica gel can be heated and made dry for reuse.
