| Abstract |
| Felspar is the seaond most imp01·tant 1·aw mate1·ial for the
pottery industry. It is also being used in the glass industry
on an inareasing seale. In spite of the inareasing use of
nepheline syenite, the use of felspar in glass industry in
Ameriaa ine1·eased to tlwee times of what it was in the
year 1935, in a pe1·iod of ten years. It is neaessary to
find out the tot.1l quantity of first gmde felspar available in
India and alwllc ont a progr,wwu~ for its aonswnption in
aeramia industry with due 1'egard to the fnture 1·equirements.
Ameriea has exhansted all Ju;r stoeTc of good qn,1lity felspa?' in
spite of the use of lttrge qnantities of nepheline syenite.
Lest we should also ltav,; to ftwe the same cliffiaulty, let us
as a first step, stop the wagtage of felspar mineral
wherever it is oeeu1·ring. In the mu:a belt of Bihar,
during mia,l mining, huge amonnt of felspar i~ being thrown
away daily as mines 1'ef1tse. This fels pa1· is mostly first
grade, high potash ancllow iron bearing mineral and as suah is
very suitable .f 01· a,:ramie zmrposes. Reeovery of thi~ felxpar
by froth flotation process has been SU[Jgested in the interest of
ee?·amia aoneerns as well as tlte owne?'S of miaa mines. Analysis
figures for several fels par samples f1·om mica mining a~·eas a1·e
given and compared with tlte an11lysis datl! for some ji?·st grade
Ame1·ican felspars. |
