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
… Europe
• Langbeinite occurs New

World Potash Reserves
• About 100
large
buried
deposits + 100 brine
deposits of commercial
potential
• The world has an
estimated 250 billionmetric tons of K2O

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 – North America
• World’s largest reserves
occur in Saskatchewan
• Ore is exceptionally high
grade (25‐30% K2O) at
depths of
950
‐1,100
m
increasing to > 3,500 m
• Uniform thickness (2.4‐3 m)
and mineralization
and
no
structural deformations
• Sylvinite, some
carnallite, and clay

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‐
carnallite).
– Mined beds

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
England
and
sylvinite
in
Spain

Potash Deposits
• Middle East:
K extracted
from
Dead
Sea
– contains an estimated 1 billion t KCl
• Latin America
– sylvinite and
carnallite

the
Sergipe
basin
in
Brazil
– KNO3 in Chile in Atacama Desert (est. 1 billion t NaNO3 and 100 million

120 million t KCl and 80 million t K2SO4
• Asia : Carnallite and K‐bearing brines in Qinghai and
Xinjiang Provinces
• Undeveloped Deposits
– Thailand, Argentina, Amazon Basin in
Brazil, Morocco, Poland, and additional deposits in the FSU

Tight supply/demand balance … new
interest in potash mining
• Saskatchewan is the world’s largest producer with
37%
of
supply
and
>
50%
of
global
potash
reserves – No potash exploration permits issued 15 years prior to
2004 … next 3 years the area under lease increased from
250,000
to
3
million
hectares – New companies … BHP Bilton, Potash One Inc., Potash
North Resource Corp., Athabasca Potash, Ivany Potash,
Sidon International Resources, Grizzly Diamonds Ltd., Alix
Resources Corp., Geo Minerals Ltd., and JSC Acron
• Estimated capital cost for a conventional mine … $2.8
billion,
excluding
infrastructure
outside
the
plant
gate
and with no production for 5‐7 years.

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
marginal given
plant’s
production
configuration
and
ramp
‐up stages
• 2012 … potential capacity should exceed demand
8/8/2019 Roberts - ASA Nutrient Cycling Symposium Potash
http://slidepdf.com/reader/full/roberts-asa-nutrient-cycling-symposium-potash 35/36
Concluding Remarks
• At present levels of production (33 Mt K2O per year)
and
with
current/planned
capacity,
the
industry
can
easily meet future demand
• Reserves (8.3 billion t) are sufficient to supply potash
for 250
years
…
another
250+
considering
the
reserve
base (18 billion t)
• Allowing for known resources (250 billion t) … there is
sufficient potash to meet demand for thousands of years
