I want to extract spinel from coarse marble. I'm crushing the rock as much as possible but I don't want to damage the spinel. Then I put it all in 20% HCL. My question, is it most efficient to bath the calcite in a gallon of 20% HCL or in two gallons of 10% HCL Is there anything else I can do to improve the process? Thanks!

Marine organisms, like corals, algae, and bivalves, play a crucial role in the biogenic formation of calcite. They extract calcium ions and carbonate from seawater to construct their shells and skeletons. Upon the death of these organisms, their calcite-rich structures accumulate on the ocean floor. Here's how the process breaks down:
