How will you get s by Frasch method?
The process involves superheating water to about 170 °C (340 °F) and forcing it into the deposit in order to melt the sulfur (melting point of about 115 °C, or 240 °F), which is lifted to the surface by means of compressed air.
Why is Sulphur extracted by Frasch process?
The low density of sulphur allows the compressed air to push it to the surface. Now, the sulphur can cool down and solidify since it is on the surface. From here, sulphur forms a rhombic crystal. Hence, in this way sulphur is extracted through the Frasch process.
How do you collect sulfur?
Sulfur is mined from both surface and underground deposits, and is recovered as a byproduct from a number of industrial processes. In sulfur mining, three techniques are applied: conventional underground methods, conventional open pit methods, and the Frasch mining method.
How is Sulphur mined?
Mined sulfur is mostly from salt domes or bedded deposits. Sulfur mining uses three different mining techniques: conventional underground methods, conventional open-pit methods, and the Frasch mining (or underground melting) method. In this process, hot water is forced into the sulfur deposit.
What is the role of water in the Frasch process?
Water in frasch process is used to heat, melt and flow sulphur deposits from underground.
Which major engineering problem is associated with Frasch process Mcq?
Which Major Engineering problem is associated with Frasch process? Explanation: Sulfur contain Shipment-insulated Barges and tank cars easily got corroded in the storage and handling process .
What is the breakage of sulfur?
Fracture
The dominant form of breakage of sulfur is Fracture.
What is the process of sulfur cycle?
The sulfur cycle describes the movement of sulfur through the geosphere and biosphere. Sulfur is released from rocks through weathering, and then assimilated by microbes and plants. It is then passed up the food chain and assimilated by plants and animals, and released when they decompose.
What Colour is sulfur?
4 days ago
pale yellow
Pure sulfur is a tasteless, odourless, brittle solid that is pale yellow in colour, a poor conductor of electricity, and insoluble in water. It reacts with all metals except gold and platinum, forming sulfides; it also forms compounds with several nonmetallic elements.
What is the most common allotrope of sulfur at room temperature?
octasulfur
octasulfur: The most common allotrope of sulfur (S8) containing eight atoms in a ring. allotrope: Any form of a pure element that has a distinctly different molecular structure.
Which commercial products is produced by Frasch process?
In the Frasch process, superheated water is pumped into the sulfur deposit; the sulfur melts and is extracted. The Frasch process is able to produce high-purity sulfur….Frasch process.

What is the use of Tyndall box in contact process?
In the manufacture of sulphuric acid by contact process, Tyndall box is used to. remove impurities. Tyndall box is for testing the presence of dust particles.
What is Frasch process in chemistry?
Frasch process. The Frasch process is a method to extract sulfur from underground deposits. It is the only industrial method of recovering sulfur from elemental deposits. Most of the world’s sulfur was obtained this way until the late 20th century, when sulfur recovered from petroleum and gas sources became more commonplace (see Claus process).
What is the Frasch method of mining?
a method of mining native sulfur in which hot water (the heat carrier) is forced into the deposit through wells to melt the sulfur, which is then brought to the surface in liquid form. The Frasch process is based on the low melting point of elementary sulfur: 112.8°–119°C.
What is the Frasch process for sulfur extraction?
In the Frasch process, superheated water is pumped into the sulfur deposit; the sulfur melts and is extracted. The Frasch process is able to produce high purity sulfur.
How deep can the Frasch process be used?
The Frasch process can be used for deposits 50–800 meters deep. 3-38 cubic meters of superheated water are required to produce every tonne of sulfur, and the associated energy cost is significant. A working demonstration model of the Frasch process suitable for the classroom has been described. ^ a b c dWolfgang Nehb, Karel Vydra.
