To improve the leaching process in the gold cyanidation, lead (II) nitrate solution is added. Although a bulk process, only amounts (10 to 100 gram lead (II) nitrate per tonne gold) is required. Both the cyanidation itself, as well as the use of lead compounds in the process, are deemed controversial due to the compounds' toxic nature.

Calcium nitrate is also the N source in this case, so application rates should not exceed the N requirement. If the recommended Ca rate is high, you may need additional Ca from another source. An additional alternative is to apply low rates of lime during a non-potato year in the rotation. Dolomitic lime will supply both Ca and Mg.

Answer: In chemistry, the suffix -ate denotes the salts of the corresponding acid in -ic. So, a nitrate is any salt of the nitric acid. For historical reasons, there are exceptions to this rule, as for example: * Hydrohalogenic acids form halides (not hydrohalogenates) * Sulfuric acid forms ...

Calcium nitrate is very hygroscopic (absorbs water from the air), so when intended for soil application, proprietary coatings are applied to minimize moisture uptake. Calcium nitrate intended for hydroponics or fertigation does not contain a conditioner, or it may be sold as a clear fluid fertilizer ready for use.
