A Better Look Into Florida’s Phosphate Mining Industry – Ethics

Phosphate is a pure, non-renewable resource that’s obtained by mining phosphate-containing minerals. Florida’s phosphate rock deposits are believed to have originated when circumstances in the seawater induced dissolved phosphorus to solidify and kind the sediment that is mined at this time (1). Sea life also played a big half in forming the sediment deposits.

An Army Corps of Engineers (5) captain first discovered River Pebble Phosphate alongside the Peace River, Florida in the late nineteenth century. Mining the phosphate began quickly after. The Florida miners had no mechanized excavation gear. That means early mining was by hand utilizing wheelbarrows, wagons, picks and shovels. The chore of mining was sluggish and labor intensive, however the phosphate pebble did show promise. Interest in this pebble will increase and the phosphate business was born.

The early twentieth century introduced mechanized excavation gear like steam shovels to the Florida phosphate mines, however steam shovels didn’t final lengthy.

Draglines were first introduced in the1920s and elevated in utilization since.

Dragline technology continued to advance, main miners to maneuver from the river-pebble to the land-pebble and arduous-rock phosphates, after which to mining the finer-grained “phosphate matrix”. Phosphate matrix deposits (4) happen over a wide space of west-central Florida recognized because the “Bone Valley”.

In 1900 it took 3 to four years to mine 15 acres with picks and shovels. Within the early days of the small draglines, about 5 acres were mined in a year. As draglines grew in measurement, draglines had been in a position to mine 500 to 600 acres a yr. Conservatively, todays draglines are in a position to fully destroy 50 acres a month.

Phosphate Mining Process

Florida’s phosphate ore (matrix) is found some 40 toes under the earth’s surface. The matrix lies intertwined with certainly one of Florida’s real treasures, aquifer systems. Phosphate rock is mined after which manufactured via the fertilizer manufacturing course of. A typical Florida phosphate mine gets about 9,000 tons of phosphate rock per acre of land.

Huge draglines are introduced in and might remove the Florida earth from the floor down 100 ft in depth so as to remove your entire matrix “area”. The phosphate trade refers the eliminated earth as “overburden”. The remainder of us name it orange groves, cattle pastures, the previous swimming hole, watersheds, aquifer systems, rivers, natural springs, and many others. Once the overburden is removed, the draglines can then “strip” out the matrix, which consists of equal components of phosphate rock, clay and sand.

The matrix (2) is then dumped in huge slurry pits where literally untold volumes of fresh clean aquifer water are used. The water comes from the newly crushed aquifers beneath the mighty dragline. Billions of gallons of Florida’s fresh water are launched and used in high-pressure water cannons to create a slurry that can then be pumped to the beneficiation plant, which will be up to 10 miles away. At the beneficiation plant the phosphate is separated from the sand and clay. Then the toxic sludge is stored in big clay settling ponds till untold amounts of aquifer water evaporate.

One by-product, referred to as phosphogypsum, is barely radioactive so it can’t be simply disposed. The one factor the miners can do with it is stack it in mountainous piles subsequent to the processing plants. Florida is such a flat state that the 150-foot-tall “gyp stacks” are normally the highest point within the landscape for miles round. They comprise massive pools that may be as large as one square mile of extremely acidic wastewater.

Not stunning, mining and mineral processing facilities generate more toxic and hazardous waste than every other industrial sector. (4) Reducing environmental impacts from giant fertilizer manufacturers operations is a national precedence for EPA.

The United States produces essentially the most phosphate on this planet, whereas Morocco and China rank second and third, respectively. Phosphate reserves are found in Central Florida, North Carolina, Utah, and Idaho. Florida is presently providing roughly seventy five percent of the nation’s supply of phosphate fertilizer and about 25 percent of the world provide.

Follow the money

Florida’s phosphate deposits at this time are the premise of an $85 billion (2) trade supplying the lion’s share of the phosphate consumed in the United States. Out of the $eighty five billion value of the business, just a few million dollars is spent on the native communities where the mines are positioned. Some have called this a boon for the local communities. However, the phosphate trade seems to be a bad neighbor. It’s because they’re “allowed” to leave their environmental catastrophes behind for those local residents to pay for. Interestingly, the Central Florida phosphate mines at the moment are known as “Bone Valley”. This $eighty five billion phosphate manufacturing space is situated in the course of certainly one of Florida’s best natural treasures referred to as aquifer techniques or “water tables”. These aquifer systems may be compared to bee hives, the place the aquifer system is the hive and the water replaces the honey. This is taken into account a basis for Florida’s complete clear fresh water supply.

Today, this Central Florida Phosphate Region (3) consists of Hillsborough, Polk, Hardee, DeSoto, and Manatee Counties. These similar counties also contain big watersheds together with the Alafia River Watershed, the Peace River Watershed, the Manatee River Watershed, the Little Manatee River Watershed and the Myakka River Watershed.

As of this text, the phosphate trade continues to purchase more land earmarked to strip mine the valuable phosphate within the watersheds mentioned above. The Florida phosphate dilemma continues to escalate, causing more intensive irreparable environmental harm each day.
