Explanation.—for the purposes of this Schedule,
“processed”, in relation to any mineral or ore, means—
(a) Dressing
through mechanical means to obtain concentrates after removal of gangue and
unwanted deleterious substances or through other means without altering the
mineralogical identity;
(b) pulverisation,
calcination or micronisation;
(c) agglomeration
from fines;
(d) Cutting
and polishing;
(e) Washing
and levigation;
(f) benefication
by mechanical crushing and screening through dry process;
(g) Sizing
by crushing, screening, washing and classification through wet process;
(h) Other
upgrading techniques such as removal of impurities through chemical treatment,
refining by gravity separation, bleaching, floata-tion
or filtration.]
