 THE MINERAL INDUSTRY OF BRAZIL 165 
vebopment. Several government agencieswere involved, and it became apparent
about midyear that these agencies disapproved the inactivity of the company.
Production of copper at Caraiba was scheduled for 1974; meanwhile, Brazil
must import $90 million worth of copper annually. 
 Iron Ore.—Production of iron ore decreased 1.4% in 197-2, while exports
increased 10.4% to 30.8 million tons. CVRD continued as the largest producer
and exporter, accounting for 84% of total iron ore exports. CVRD's production
of 26.9 million tons came from its mines at Itabira in the following quantities:
Caué mine, 19.0 million tons; Conceçfio mine, 7.6 million tons;
and the Picarrflo mine (opened in June), 300,000 tons. CVRD announced that
production of "gravel" and run-of-mine fines will cease in 1973. Its concentrator
and washing plant at Itabira will produce instead washed fines products,
consisting of sinter feeds (plus 1 millimeter, minus 1 millimeter plus 0.6
millimeter, and minus 0.6 millimeter plus 70 micrometers) and pellet feed
(minus 70 micrometers). As production at the Caué mine declines, the
20-million-ton washing plant will be fed with increasing quantities of fines
-from the 30-million-ton stockpile, which has accumulated over a number of
years. 
 The Picarrão property contains a reserve of 35 million tons of ore
and will produce 3 -million tons annually. Some of the ore is itabirite (44%
Fe), and research into applicability of wet high-intensity magnetic separation
is being conducted. 
 The joint CVRD-US. Steel Co. drilling of an iron deposit in Serra dos Carajas,
Pará, was completed in January. A reserve of 1.6 billion tons of 67%
grade was measured, and an additional 9.5 -billion tons indicated and inferred.
The ore body, which lies between the Xingu and the Tocantins Rivers, consists
of both hard and earthy hematite, the hard hematite amounting to about 25%
of the total. Production may begin in 1977 if problems of transport are solved.
 Early in 1972, Vale do Rio Doce Navegaçao S.A. (Docenave), the ore
carrier fleet subsidiary of CVRD, placed the M.V. Doceangra in service. The
ship, at 56,500 deadweight-tons, was the largest built in Latin America.
In May, a record 168,530 
tons of iron ore was loaded on the M.V. Berge Istra. In July a monthly record
of 2,822,521 tons was loaded out in 39 vessels. CVRD nevertheless intends
expanding its 
port facilities at Tubarão from the present 28-million-ton bevel to
50 million tons per year, and eventually 80 million tons. The railroad from
Itabira to the port area is now being double-tracked. Facilities under construction
at TubarAo in 1972 included land reclamation, a 2-million-ton ore yard, a
16,000-ton-per-hour sampling plant, an ore-loading -berth, an approach channel,
and a turning basin designed for 250,000ton ore carriers. A pelletizing plant,
capable of producing 2 million tons per year, is now in full operation. Construction
of 3.2 million tons of additional capacity will begin early in 1973, and
further expansion to an ultimate 11 ' million tons is planned. S.A. MineraçAo
da Trindade (SAM!TRI) has joined with the Marcona Corp. to form Samarco Mineracflo
S.A., whi-ch will evaluate SAMITRI's low-grade reserves. In addition to a
present annual export capacity of 6.5 million tons, SAM!TRI intends to produce
4.4 million tons from its properties at AlegrIa, Minas Gerais. 
 A deposit of iron ore reportedly larger than that in the ' Serra dos Carajas
has been discovered in the northern part of Amapá territory. The deposit,
of grade similar to that at Carajas, is ' much nearer to water transportation.
 CVRD conducted a resolute campaign to sell Brazilian iron ore abroad. As
a result, 44 million tons of CVRD ore will be delivered to various furnaces
in West Germany over a 15-year period. Ferteco, S.A., a Brazilian iron mining
company affiliated with German steel interests, obtained as part of the agreement
the right to export 64 million tons during the same period, using CVRD's
railroad and port facilities at Tubarflo. As a further result, ' Brazil is
to obtain power-station equipment from Czechosl-ovakia in return for $50
million worth of iron ore, delivered over a 12-year period at about 300,000
tons per year. 
 Mineracôes Brasileiras Reunidas, S.A. (MBR) conducted preliminary
work at the Aguas Claras mine near Belo Horizonte, and began building -port
facilities on Guaiba Island in Sepetiba Bay, west of Rio de Janeiro. The
port will accommodate ships of up to 250,000-ton capacity.
