Economic analysis model for lithium production by Direct Lithium Extraction (DLE) method from a single well

Abstract

The article presents an economic model enabling the assessment of the profitability of lithium extraction using the direct lithium extraction (DLE) method from geothermal brines from a single well. The model enables a preliminary simplified assessment of the profitability of DLE projects, which can be helpful in selecting the optimal locations for such projects and drilling production wells. The article also presents the critical role of lithium as a raw material for the decarbonization of the world economy, methods of its extraction and the economic prospects of the market for this raw material. It also presents exemplary DLE projects in the world.
