Summary: In the paper the results of many years of archival and
fieldinvestigations in the history of bauxite mining of the threeauthors
are presented. It was established that in Istria in thevalley of the river
Mirna beneath the Castle of Sovinjak bauxitewas exploited already 400 years
ago, and that 1808 about this orethe first scientific account was
published. Accordingly, thestatements in the professional literature that
the first bauxitemine opened 1873 in the French Provence and that the
bauxite orefor the first time was scientifically described 1821 have to
berevised. About this necessary revision here the essential proofsare
produced.

Summary: The hydrocyclone of 25 mm diameter has been tested on the
laboratory hydrocyclonic device. There have been varied the values of
relationship Du/Do, the concentration of feed suspension and the greatness
of pressure. With the suspension of fine grindeed limestone and water there
have been examined 36 combinations of various values for the mentioned
variables. The optimal efficiency of the liquid in the overflow has been
achived by the relationship Du/Do=0.73 ranging from 70...80 % with the
concentration of the solids in overflow from 0.3...1.5 % and cut size of
0.004...0.006 mm. There have been shown three schemes of separation of
drilling fluids proposing the application of multicyclones instead of
centrifuges in the final phase of cleaning the fluids.

Summary: Reclamation of open-pits tailing sites, neutralizing of
acid minewater and protection against spontaneous coal combustion
arecarried out very succesfully nowadays. New mineral
processingtechnologies make possible considerable reduction of ash
andsulphur content in coal. The application of the so called
"clean"combustion technologies helps reduction of solid refuse mass
andgaseous pollutants emission. The protection measures used insingle
exploitation stages and the most promissing technologiesof coal processing
and combustion are presented.

Summary: New coal combustion technologies as also more rigid
regulationsof environmental protection, require coal of higher heating
valuewith least possible ash and sulphur content. By traditionalprocessing
methods it is possible to achieve 7 to 13% ashcontent, while the major
sulphur partion remains in coal evenafter processing. The new processing
technologies helps to reduceash below 5% and sulphur below 1%. Some of the
most prospectivetechnologies are presented in this paper.

Summary: As a result of the expanding metal consumption in the world
andthe increasing exploitation of lowgrade ore deposits, miningtailings
continue accumulating.Their disposal gives rise toecological problems.
Special problems occur with wastes thatcontain various noxious constituents
(haevy metal ions, flotationreagens, acids and others), which may seriously
endanger thequality of surface and undergruond water. One such waste is
redmud, which, besides great amounts of very fine particles andFe-oxides,
contains a significant quantity of extremely dangerousNa-oxides. The paper
discusses the red mud disposal systemsapplied, in teh areas of former
Yugoslavia. Possible noxiousenvironmental influences of these deposits and
the protectivemeasures are brought forth.

generalunderstanding of design and operating characteristics
ofhydrocyclones, especially those with small diameter. Practicalaspects of
hydrcyclones design, operation installation,selection, scale-up and
spesific applications are to be furtherdeveloped. It is also nedeed to
develop applicable model whichwould give reasonable predictions over a wide

Summary: A very extensive research by computer for a triplane
(81,16,3) iscarried out. The main result is: If there a symmetric
(81,16,3)designed at all exists, then it has no automorphism group G=A5.
The construction of triplane (71,15,3) with the automorphismgroup G=F8*F21
is presented. The folowing results are obtaned:Together with their duals
there are nine nonisomorphic triplanes(71,15,3) with the automorphism group
E8*F21. One of these isismorphic to its dual.
Keywords: incidence structure, symmetric design, automorphism, orbit structure, classification

Summary: A design with parameters (v,k,lambda) is such a family of
vk-subsets (blocks) of a set consisting of v elements (points)that each two
blocks have exactly lambda common points. Theexistence of the design
(121,16,2) allowing an automorphism groupisomorphic to A4 has been
investigated. It is proved that such adesign does not exist.
The complete classification of the design (78,22,6) with anautomorphism
group isomorphic to E8*F21 is carried out. Theconstruction of all designs,
which is based on the investigationof the group acting, was performed. It
was find out that thereare (up to isomorphism) exactly two mutually dual
designs of thattype.

Summary: A series of experiments were carried out in an effort to
revealthe effects of the major dimensional and operational varibles(cyclone
diameter, vortex-finder and apex diameter, feed pressureand solid content
of the feed slurry) on the separationpossibilities of a hydrocyclone. The
mathematical model developedby Plitt (1976) which consists od four basic
equations expressingthe cut size, volumetric split between overflow,
volumetricthroughput, and sharpness of separation, was used. The model
ismodified for small diameter hydrocyclone, allowing hydrocyclonesoperation
prediction without previous experimental work.
