Metal detectors are being deployed in major cities across Brazil to detect the metal coming from the mines that are fuelling violence in the country.
Metal detectors have been installed at airports and train stations across the country to help track down those who are illegally transporting large amounts of metal.
The metal detector is also being used to detect small amounts of lead and zinc in the soil.
Metal detectorist Daniel Guimaraes said that in some places, metal detectors have stopped people from carrying out their jobs, but that it had been a success.
Metal detection technology “We know there are a lot of metal detector users here.
We are doing everything we can to make sure the detection system works.
But we also want to make it as safe as possible for everyone,” he said.
“This is our job.
It is a public service.
We need to help the people of Brazil.”
Brazil has been hit hard by violence in recent years.
In June, the government banned the use of leaded petrol and petrol blends that contain lead.
The government also launched an investigation into whether companies were using the metal detectors to track down illegal miners.
