Government spokesman Alex Contreras said a "social truce" had been agreed to.
The conflict erupted after an estimated 4,000 miners from independent cooperatives demanded access to the giant tin mine.
Miners had hurled dynamite and fought gun-battles for two days running, throwing up a serious challenge to left wing President Evo Morales.
The independent miners rolled tyres loaded with dynamite down slopes to the mine, blowing up mine ventilation equipment.
State workers retaliated by blowing up a housing complex for the independent workers' families.
The government sent in 700 police to the Huanuni mine complex to restore order.
A short overnight truce allowed the two sides to collect bodies before the clashes this morning resumed around the remote mining region, 4,000 metres up in the Andes and 500 kilometres south of La Paz.
Huanuni produces five per cent of the world's tin. Prices on world markets soared yesterday following the violence.
The independent miners and workers for the state-owned Mines of Bolivia (COMIBOL) are both linked to Bolivia's president.
Mr Morales, Bolivia's first indigenous president, came to power promising to spread the wealth from the country's rich natural resources. He has forced foreign oil and gas companies to renegotiate contracts but has faced mounting troubles in the mines.
