Reaching a capacity to produce 40.000 tons high-grade (42-52% Cr2O3) blended chromium in recent years with open-pit mining and partially underground method, Akmetal is the biggest concentrate producer in the sector today with a capacity to produce 240.000 tons of concentrate/year that it has reached by producing and processing circa 2 million ...
Which mineral crystallizes, calcite or aragonite, depends on the water chemistry. Seawater is full of ions that compete with calcium and carbonate. Magnesium (Mg 2+) clings to the calcite structure, slowing down the growth of calcite and forcing itself into calcite's molecular structure, but it doesn't interfere with aragonite.

Aragonite Wikipedia. Aragonite is a carbonate mineral, one of the three most common naturally occurring crystal forms of calcium carbonate, Ca C O 3 (the other forms being the minerals calcite and vaterite).It is formed by biological and physical processes, including precipitation from marine and freshwater environments.
respect to aragonite. In this case, aragonite will precipitate or follow the left to right chemical reaction of equation (1). When Ω < 1, the seawater is said to be undersaturated with respect to aragonite, which results in the aragonite mineral dissolving or following the right to left chemical reaction of equation (1).

Aragonite Group. The Ca analogue of strontianite. The principal member of the Aragonite Group, aragonite is the second most common polymorph of natural calcium carbonate (the most common is calcite).It is significantly less widespread and abundant than calcite and is formed under a much narrower range of physiochemical conditions.
Aragonite. Aragonite is a polymorph of calcite. In hand sample, it can be distinguished from calcite by its lack of rhombohedral cleavage and, in sufficiently translucent samples, its lack of double refraction. Physical Properties. Chemical formula. CaCO 3. Class. Carbonate. Crystal system.
The first commercial production of phosphate rock began in England in 1847. A wide variety of techniques and equipment is used to mine and process phosphate rocks in order to beneficiate low-grade ores and remove impurities. The eighth chapter of this book deals with mining and beneficiation of phosphate ore. The principle and operating conditions of important parts of …

Biominerals based on calcium carbonate are found in a very large number of organisms. The shells of molluscs are among the most abundant biogenic minerals, and are composed of 95% to 99% calcium carbonate crystal and less than 5% organic matrix.Shell layers are formed from calcium carbonate as aragonite or calcite crystals, corresponding to different mineral textures (also called microstructures).

Aragonite and calcite are dimorphous or polymorphs. They share the same chemistry but have different crystal habits. While calcite is the most abundant and widespread carbonate mineral on Earth, aragonite is less so. Facetable aragonites are almost always very small, as opposed to calcites, which occur in huge, transparent masses or crystals.
"Any potential mining area, once stripped of aragonite will take hundreds if not thousands of years to recover. Ocean Cay where mining occurred for 40 years, shows no sign of recovery." In 2018, the Ministry of the Environment commissioned a study into the economic value of and quantity of aragonite deposits in The Bahamas.
