| Abstract |
| The paper deals with the utilization of the sludge
left after the recovery of potash from felspar for the purpose
of making good quality bricks. The sludge from the dry
method of the potash recovery contains inert silicates
produced at high temperature and gypsum, which adversely
affect the bonds in the bricks, and yields bricks of comparatively
low strength. The sludge of the digestion
process is suitable for making bricks having high compressive
strength, nearly ten times that of ordinary clay bricks.
Purer the lime used greater is the strength of the bricks.
The process provides a method for utilizing felspar cheaply
and extensively available in the country for producing
potash, a valuable chemical and fertilizer, and bricks of
high compressive strength. Preliminary cost estimate
indicates, that the process is commercially feasible. |
