Question

Which of the following processes is used for recycling of silica sand or dust in foundry during the casting process?

(a) Radiography

(b) UV method

(c) Abrasive blasting process

(d) Finn method

I got this question in my homework.

My question is based upon Foundry Environment Health and Safety topic in portion Foundry Environment Health & Dust Problem in Foundries of Casting-Forming-Welding I

Answer 1

The correct answer is:

(d) Finn method

The Finn method is a process used in foundries to recycle silica sand or dust, helping to manage waste materials during the casting process. This method allows the reuse of sand that has been contaminated with binder material by removing it through mechanical and chemical processes, making it suitable for reuse in casting.

The other options are unrelated to the specific process of recycling silica sand or dust in foundries.
