The 2011 edition Guiding Catalog of Industrial Structure Adjustment (the Guiding Catalog 2011), released by National Development and Reform Commission (NDRC) ofChina, effectively regulatesChina’s phosphate industry.
The Guiding Catalog 2011 divides all industries into different types of encouraged, restricted and eliminated. Among the encouraged industries, NDRC’s encouragements are:
– exploiting and utilizing low grade phosphorus ore and its associated ores;
– full heat recovery thermal phosphoric acid production;
– setting up large-scale production line of calcium phosphate with defluorination device;
– comprehensive ardealite utilization and wet phosphoric acid purification device with capacity above 100,000t/a;
Besides, NDRC also encourages phosphoric acid iron battery materials. Meanwhile, NDRC restricts the development of some phosphate chemicals with characters of overcapacity, high energy consumption and heavy environmental pollution. The restricted type related to phosphate industry includes:
– new sulfuric acid production lines with unit production capacity below 300,000t/a (sulfur burning process) and 200,000t/a (pyrite-based process);
– new plants of STPP, PCl3, P2S5, feed grade calcium hydrogen phosphate, sodium hexametaphosphate, etc.;
– new production line of yellow phosphorus with unit capacity below 30,000t/a;
– new production device of ammonium phosphate fertilizer;
– new production lines of glyphosate, triazophos.
The eliminated types related to phosphate chemicals are some inefficient capacity includes unit production capacity that is below 100,000t/a (both sulfur burning and pyrite-based); unit capacity below 5,000t/a and the devices which can not meet the requirements listed in Entry Criteria; unit capacity below 10,000t/a (STPP), 5,000t/a (sodium hexametaphosphate), 5,000t/a (PCl3) and 30,000t/a (feed grade calcium hydrogen phosphate).

CALCIUM: One of The Essential Slow Carb Vitamin
Calcium carbonate and calcium citrate are the two most commonly used forms of calcium.
Calcium supplements are usually divided into two doses daily in order to increase absorption. It’s best to take calcium with food in doses of 500 mg or less.
If you have a reduced stomach acid level (i.e you take antacids) you’ll be able to absorb calcium citrates more easily than calcium carbonates. Calcium citrate malate is especially useful if you suffer achlorydia, a lack of gastic stomach acid secretion, or hypochlorydia, which are low levels of chloride in the blood.
For heartburn: Calcium carbonate as an antacid is usually 0.5-1.5 grams as needed. (this is a reason to choose calcium cabonate over calcium citrate)
Other Considerations
It’s also beneficial to combine calcium with vitamin D as your body requires this vitamin for optimal calcium absorption.
As part of the Slow Carbohydrate Protocol you may want to combine Calcium with Magnesium and take a separate vitamin D supplement as it is almost impossible (but not if you want to take a lot of pills) to get a combination that supplies the recommended daily allowance of all three.
CALCIUM:What is it?
Calcium is a mineral that is an essential part of bones and teeth. The heart, nerves, and blood-clotting systems also need calcium to work.
Calcium is used for treatment and prevention of low calcium levels and resulting bone conditions including osteoporosis (weak bones due to low bone density), rickets (a condition in children involving softening of the bones), and osteomalacia (a softening of bones involving pain). Calcium is also used for premenstrual syndrome (PMS), leg cramps in pregnancy, high blood pressure in pregnancy (pre-eclampsia), and reducing the risk of colon and rectal cancers.
Some people use calcium for complications after intestinal bypass surgery, high blood pressure, high cholesterol, Lyme disease, to reduce high fluoride levels in children, and to reduce high lead levels.
Calcium carbonate is used as an antacid for “heartburn.” Calcium carbonate and calcium acetate are also used for reducing phosphate levels in people with kidney disease.
Calcium-rich foods include milk and dairy products, kale and broccoli, as well as the calcium-enriched citrus juices, mineral water, canned fish with bones, and soy products processed with calcium.
Calcium can interact with many prescription medications, but sometimes the effects can be minimized by taking calcium at a different time. See the section titled “Are there any interactions with medications?”
