(Correct spelling of Corfo in headline, first and second paragraphs)

SANTIAGO, Dec 18 (Reuters) - Chilean development agency Corfo and Pampa Calichera, which controls lithium giant SQM , have agreed to suspend their arbitration battle for 30 days as they make a new push to solve a dispute over mining claims, Corfo said on Monday.

If the negotiations are successful, Chile would be able to expand its lithium production "significantly," Corfo said in a statement. Corfo has accused SQM of failing to fulfill requirements to pay royalties and of violating environmental rules.
