Question

Sand reclamation is defined for repeatedly using new sand for the making of moulds in production of castings.

(a) True

(b) False

The question was asked during an interview.

I'd like to ask this question from Sand Reclamation Techniques in section Sand Reclamation & Control Test of Casting-Forming-Welding II

Answer 1

Right choice is (b) False

Easiest explanation: Sand reclamation is a physical and chemical treatment of used foundry sands so that they can be reused in making of cores and moulds for the production of casting components. The true reclamation cleans each and every single grain within the sand, whereas reconditioning is defined for the partial cleaning and treating of sand mass.
