Argentina: Sit-in protesters from the Argentinean Mining Workers Association (AOMA) have blocked access to the hoppers of limestone crushers at Minerar’s Olavarría quarry, according to the Clarín newspaper. The quarry supplies limestone to Loma Negra’s La Amali cement plant.
The cement producer said “The biggest problem is that if they don't solve the problem, and stop the supply raw material, it will complicate cement production."
