Copper Concentrator Plant Supplier

Copper Concentrator Plant Supplier

Bechtel completed—ahead of schedule and under budget—the $270 million expansion of a copper concentrator plant that Bechtel originally designed and constructed at the Collhahuasi copper mine in Chile. The company completed the original concentrator in 1999.

Collahuasi is the world’s third-largest copper mine. The 62,000 ton-per-day expansion project more than doubled the plant’s capacity.

Collahuasi was one the world’s highest, harshest job sites. Stranded 4,800 meters above sea level in the Andes and surrounded by northern Chile’s brutally barren Atacama Desert, the copper mine is subject to conditions that are unprecedented, and unrelenting. Breathing is a struggle in the thin air. Temperatures rarely top 11 degrees Celsius during the day and normally plunge below freezing at night. Ferocious blizzards, lightning storms, and active volcanoes batter the region. There are no trees, signs of animal life are rare, and humans are almost unheard of—the nearest settlement is nearly 100 kilometers away.

Bechtel began work on Collahuasi in December 1995, facing a formidable task. Collahuasi wasn’t just about building a copper mine. There were five major construction projects under the overall umbrella: a copper concentrator plant; a copper solvent extraction plant; a 190-kilometer-long copper slurry pipeline; new deep-water port facilities at Punta Patache; and a raft of infrastructure facilities at both the mine site and the port, from buildings and utilities to deep well pumps and a sewage treatment plant. And there were auxiliary projects as well. The team had to build a 190-kilometer paved road to the site, as well as service roads, well fields, and even a new mine airport.

It was an ambitious agenda that called for up-front legwork and strategic planning.

Not surprisingly, high-altitude issues figured prominently in this front-end phase—after all, aircraft are pressurized at 4,800 meters. The Bechtel team had to address everything from productivity, morale, and altitude sickness to special safety and construction issues. Workers underwent thorough medical examinations before venturing to the site, and again whenever they arrived at high elevation. Testing included a pulmonary exam, respiration test, blood-oxygen test, chest X-ray, and ekg. About 25 percent of the applicants couldn’t make the cut. To maintain productivity, the 12,000-plus construction contractors, craftspeople, laborers, and management personnel worked a schedule of either 20 days on-site and 10 days off, or 10 days on-site and 5 days off.

Dolomite Processing

Dolomite is a magnesia-rich sedimentary rock resembling limestone. For dolomite processing, SBM will provide you with best dolomite crushers and dolomite mills.

Due to its features like increased hardness and density, dolomite is widely used in glass making, ceramics, steel making, agricultural PH control, construction and building.

Dolomite mining is important in heavy industry. To process dolomite, firstly dolomite is burnt, hardened and then made into small pellets and heated again. These pellets of dolomite are then used in the manufacture of blocks of dolomite refractory.dolomite processing plant
