WHO WE ARE
Head OfficesThe head offices of the Group are located in Saltillo, México.
The QuarryThe gypsum Quarry is located in the in the Sea of Cortez, 460 miles / 740 kilometers South of San Diego, Ca.
Port is located within property limits, 3.75 miles / 6 kms. from the quarry.
The process of mining starts with the exploration works. This is done by drilling coreholes into the gypsum deposit. The core holes are drilled according to an established pattern in order to form a grid over our gypsum property.
Once the exploration works are finished for each area, we proceed to develop a quality map of the deposits in that area. This map details the tonnages and quality of the gypsum in a tri dimensional model.
MINING OF THE GYPSUM ROCK
Once the area is cleaned we drill blast holes. These holes are drilled at an average depth of 12 meters to form benches. The holes are then filled with explosives and blasted to fragment the gypsum rock at a maximum size of 40 inches per side.
FROM THE MINE TO THE PLANT
The primary crusher reduces the size of the gypsum from a maximum of 40 inches to a maximum of 10 inches per side. The capacity of this crusher is 800 tons per hour. from the primary crusher the gypsum is move to the secondary plant by a 5 kilometer conveyor belt.
SECONDARY CRUSHING-SCREENING-TERTIARY CRUSHING
In the secondary plant the gypsum is reduced from -10 inches to 3 different sizes, -6 inchs, – 2 1/2 inches, and -1/2″ of an inch. From the secondary plant the gypsum is transported to the stockpile if finished product.
When the gypsum gets to the stock pile, it is ready to be shipped and used by our customers. Most (+95%) of our product is shipped by vessel.
