If the company manages to cut leverage by securing stable revenues and profitability through higher sales of
barytes, Fitch could revise the outlook to "stable".
Mineral fillers and extenders include phlogopite mica, platy talc,
barytes, and calcium carbonate.
Mineralization occurs at different levels, as typical strata-bound deposits and in vein-type discordant bodies, generally characterized by manganesiferous siderite and subordinate
barytes and sulphides (Rodeghiero and Zuffardi, 1985, 1988; Cassinis et al., 1997a).
Hidden past: Force Crag Mine at the head of Coledale Valley, Cumbria, opened in 1839 and was mined for lead, zinc and
barytes before being finally abandoned in 1991.
The heavy fraction of carbonate rocks consisted of goethite and hematite (average 30.4%), transparent heavy minerals (22.9%), ilmenite and magnetite (21.6%), pyrite (14.1%), biotite (4.8%), muscovite (2.1%),
barytes (1.8%), leucoxene (1.7%), and chlorite (0.6%) (Table 3, Fig.
There are rich deposits of limestone, coal,
barytes, gypsum, and feldspar.
Blacks (carbon black, synthetic black iron oxide); Extender pigmerits (sparmite
barytes); Greens (chromium oxide); Reds (copperas red, kroma red, natural), Yellow and Oranges (UltraYellow, Ferritan).
Lead, iron ore, zinc,
barytes and fluorspar are also mined in the northern coastal region and in the north-west.
Bolan Mining Enterprises (BME) a 50:50 Joint Venture between PPL and the Government of Balochistan, sold a total of 13,213 ton nes of
Barytes powder/ore during the year under review, compared with 13,817 tonnes in 1998-99.'
Richard Mozley's MeGaSep multigravity separator is designed to separate all fine and ultra-fine particles, and has applications in the recovery of precious metals, base metal oxides and sulphides, and the upgrading of industrial minerals such as fluorspar, celestite and
barytes. According to Mozley, it now provides the capability to clean previously untreatable and uneconomical fine coals or waste materials without the use of environmentally harmful physical or chemical agents.
Painters and paint manufacturers experimented with zinc-oxide, zinc-sulphide,
barytes, and carbonates, with mixed but largely encouraging success, producing a range of new products: some cheaper, some whiter than white lead, and some, they claimed, every bit as durable.
