It can vary in purity, consistency and hardness. The limestone can be a soft chalky material with microfossils, a hard recrystallized mass, a grainy sand-lime mass, or a mass of fossil corals, urchins and shells.

The dragline bucket holds from 45 to 65 cubic yards of material and is large enough to hold a truck or van.  It scoops up the top 15 to 30 feet of earth, known as overburden, and dumps it in spoil piles to the side of the mine pit. The dragline then digs out the ore-bearing layer (known as the matrix), which consists of about equal parts phosphate rock, clay and sand.https://floridadep.gov/water/mining-mitigation/content/phosphate
