Figure 2. Mineral raw material for technological sample
It could be seen from diagram that the
lime as mineral raw material is the most
present in the approved SMP for taking
the technological samples, then marble,
dolomite, diabase and other raw materials.
The share of metal ores in percentage distribution
of raw materials is, as it could be
seen, insignificant in comparison to the
non-metals.
Determining the quality of mineral raw
materials in deposit, that is the ore body,
is determined by sampling and prescribed
by the Regulation on classification and
categorization of reserves the solid mineral
raw materials and keeping records of them
(“Official Gazette of SFRY” No. 53/79).
Quantity of mineral raw materials, are
dijabaz, 5.6%
andezit, 5.6%
dacit, 3.7%
pesak, 3.7%
glina, 3.7%
olovo i cink, 3.7%
tuf, 3.7%
not clearly defined in this Regulation
rules, except for architectural-construction
stone. Due to this reason, MME have
brought an act that clearly prescribed and
adjusted amounts of mineral raw materials
that can be exploited for the purpose of
taking samples for technological investigations
(Table 1).
Therefore, quantity of material that can
be taken as a technological sample should be
determined in accordance with these terms.
For the following method, after realized
mining works, there is no need for land reclamation
on surface where the sample was
taken, as well as land restoring to the original
purpose, what were the main reasons for
enactment of this Act by the Ministry.
