Potassium (K) and Potash

• K present in most rocks 

and soils

• Economic sources … 

 – sedimentary salt beds 

remaining 

from 

ancient 

inland seas (evaporite 

deposits) 

 – salt lakes and  natural 

brines

• Potash refers to a 

variety of  K‐bearing 

minerals

Common K Minerals

• Sylvite (KCl) … abundant in 

commercial deposits

• Sylvinite (KCl + NaCl) also 

common 

• Hartsalz … ore deposits with 

SO4 salts (kieserite [MgSO4] or 

anhydrite 

[CaSO4]) 

are 

limited

World Potash Reserves

• About 100

Potash Resources and Reserves

• Resources include proven, probable, and inferred 

reserves

 – Reserves: deposits

 of 

 sufficient

 quantity

 and

 quality

 that

 are

 

currently mined

 – Reserve base: reserves + deposits that are marginally 

economic or

 sub

 economic

• U.S. Geological Survey estimates global reserves at 18 

billion t K2O

 …

 8.3

 billon

 t considered

 commercially

 

exploitable.

Potash Deposits – FSU

• FSU has extensive proven reserves of  K minerals … second only 

to the deposits in Saskatchewan

• Russia 

 – Verkhnekamsk 

deposit 

in 

the 

Urals 

near 

Solikamsk – Potash depth at 75 to 450 m in 13 potentially minable beds ranging in 

thickness from 26 to 30 m (sylvinite) and 70 to 80 m (zone of  sylvinite‐

Potash Deposits – Western Europe

• Oldest deposits are the Hessen and Thüringen  beds 

in southern Germany

 – contain 15

 to

 20%

 sylvite,

 kieserite,

 and

 carnallite

 (~10%

 

K2O)

 – Beds are relatively flat‐lying, but also folding, with some 

barren zones,

 sudden

 thickness

 changes,

 etc.

 making

 

mining difficult

• Also carnallite and kieserite deposits in central 

Germany and

 sylvite

 and

 carnallite

 in

 northern

 

Germany

• Sylvite deposits

 in

Concluding Remarks

• Global potash supply/balance will remain tight 

through 

2012 – During this time demand will absorb capacity increases

 – Potential surplus … 2.2 and 3.9 Mt K2O, which is considered

8/8/2019 Roberts - ASA Nutrient Cycling Symposium Potash

Concluding Remarks

• At present levels of  production (33 Mt K2O per year) 

and 

with 

current/planned 

capacity, 

the 

industry 

can 

easily meet future demand

for 250

 years

 …

 considering

 the
