Blends

Calcimag Limestone & Dolomite Blends

Longcliffe produces several blended products at our various quarry sites in Derbyshire in order to supply the vast agricultural industry with the screened limes they demand. Our operations include the production of Calcimag, a specific blend of granular calcium and calcium-magnesium carbonates, derived from very high-purity carboniferous limestone and dolomite. All products are crushed and screened for improved size accuracy, resulting in a granule size of less than 3.35mm. Calcimag is a fast-acting liming product capable of neutralising acidic soil, resulting in increased fertility. It has a high neutralising value (NV) and provides essential calcium and magnesium minerals to the soil. Our facilities and operations are fully accredited with ISO 9001 and ISO 14001, ensuring our products are some of the best on the market.
 

Properties and Benefits

Properties

Calcimag is a very diverse material consisting of a blend of both dolomite and limestone. The typical physical properties of Calcimag are outlined below:
 
Appearance grey/buff granules
Total neutralising value* 56.5%
Calcium Oxide (%) 43.5
Magnesium Oxide (%)  10.4
Typical Moisture (%)  2
Granule Size nominally <3.35mm

*CaO equivalent on a dry weight basis. If you have any further enquiries or need more specific information, please call our sales office on 01629 540284 to request a technical datasheet.
 

Grades

Grades

Calcimag is nominally less than 3.35mm, providing an even texture for application. All of our operations are fully accredited to ISO 9001 and ISO 14001 so you can be sure you are receiving reliable products from our quarries. If you need further information on specific grades please speak with a member of our team who can provide you with the relevant technical datasheets. 

Packaging

Packaging

All agricultural liming products are available in bulk for our customers both locally and nationally. Calcimag can be supplied from stock in bulk tipper vehicles delivered direct to farms. Alternatively, Calcimag is available for collection from our quarry at your own convenience.

We take pride in the quality of our material and delivery services and take advantage of our own dedicated fleet, as well as our approved contractors, to ensure our customers receive their products on time. At Longcliffe, we understand the importance of being reliable in the demanding agricultural market.
 

REACH

REACH

Both Limestone (CAS: 1317-65-3 & EINECS: 215-279-6) and dolomite (CAS: 16389-88-1 & EINECS: 240-440-2) are exempt from the obligation to pre-register under the REACH legislation. The exemption is granted in Annex V, Entry 7 as the material is a naturally occurring mineral and has not been chemically modified.
