Fluid Control Equipment Industry Uses Corrosion-Resistant Material, Which Contributes to Sustainability in Mining

After the environmental tragedies experienced by Brazil, society is attentive to all kinds of soil and water contamination. The mining sector has managed to modernize to respond to this. While large dam systems were once the norm, the priority today is to manage these waste materials, which depends on specific systems and equipment. With the modernization of the sector, the demand for technologically advanced equipment is growing. Read also: 250 job openings at the mining company Terra Brasil Minerals.

This is a sector responsible for 2.5% of the national GDP, generating over R$ 50 billion in revenue and royalties annually, and around 3 million direct and indirect jobs, according to the Ministry of Mines and Energy. To implement the Mining and Development Program, which aims to attract new investments and promote mining development by 2023, new technologies are required.

“Even with the new system, which subjects waste to drying processes, it is necessary to transport this material to its destination without contamination risks,” explains electrical engineer and general sales manager for the industrial area at GEMÜ, Mateus Souza. For this, valves and other fluid measurement and control equipment promote environmental safety. Designed to withstand the abrasiveness of compounds resulting from mineral extraction, they prevent leaks.

In the mining process, valves are used in “filter press,” equipment utilized in separation processes between solids and liquids, operated by pressure. The method involves pressurizing the waste slurry in filters that separate all the water from the solid material for treatment and release of a dry solid residue. “Proper storage of this waste is essential to avoid environmental damage,” the engineer explains.

An important detail is that the waste slurry, composed of mineral remnants, sand, and water, is corrosive and requires equipment made from resistant materials.

“Unfortunately, it is quite common to have accidents due to poor product choice, which is why it’s important to have an initial disposition to make the right choice,” Souza reminds.

With the right technology, it is possible to advance in soil recovery processes and sustainability acrossall production chains.

About GEMÜ – The branch of the German multinational founded by Fritz Müller in the 1960s offers the Brazilian market extremely efficient and high-quality valves. The plant located in São José dos Pinhais (PR), which has 100 employees and is completing 40 years in 2021, produces valves and accessories for water and wastewater treatment in industries across all sectors, such as steel, fertilizers, and automotive, as well as for integrating energy generation systems. In the PFB area (pharmaceutical, food, and biotechnology), GEMÜ is a world leader and sells high-precision products throughout Latin America, providing local support and consulting from professionals capable of guiding the choice of the best valve solution for each application.

Is a smart plug worth it in a regular home? What does it offer: turns on and off via smartphone, creates routines by schedule, prevents forgotten devices, sometimes monitors consumption, and improves habits without renovation or miracles.

Geographers redefine the Brazilian relief and confirm the presence of mountains in 14 states with a new system that changes historical criteria and alters the way the territory is classified.

Archaeologists have discovered a colossal submerged wall in the Atlantic, dating back 7,000 years and weighing 3,300 tons, regarded as the largest prehistoric submerged structure ever found in France.

There is a city in China right next to Hong Kong where people speak Portuguese, the streets have names in Portuguese, and the architecture looks like it came straight out of a historic city in Brazil.

At over 8,800 meters above sea level, the summit of Mount Everest is made up of rocks that originated at the bottom of an ocean about 500 million years ago and were pushed to the highest point on Earth by the collision of tectonic plates.

On the Greek island of Ithaca, archaeologists have found what may be a sanctuary dedicated to the legendary Odysseus, with inscriptions bearing his name and votive offerings that span from the Mycenaean to the Hellenistic era.

Researchers at the University of Surrey have discovered that simply NOT removing water from a battery material can double its capacity, and as a bonus, the same system can desalinate seawater while storing energy.

Scientist who “predicted” the pandemic issues new warning, says the world may be entering a phase of disintegration and urges us to prepare for what is to come.

While BYD lays off 100,000 in China due to falling profits, the factory in Brazil remains strong: the unit in Camaçari, Bahia, could generate up to 20,000 jobs and become an export hub for all of Latin America.
