The salt lake DLE lithium extraction industry is plagued by a common predicament: promising pilot test results fail to translate into stable industrial operation. While lab facilities and kiloton-scale pilot plants can consistently hit target indicators, scaling up to ten-thousand-ton production lines triggers a host of issues including reduced lithium recovery, extraction emulsification, frequent membrane fouling, and material imbalance. These problems prolong project commissioning timelines and drive up enterprises’ operation, maintenance and raw material loss costs. The core root cause of failed scale-up lies in the lack of complete standardized scale-up systems among most technology service providers. They merely apply fixed process parameters based on static pilot data, which cannot adapt to real working conditions of large-scale equipment such as complex fluid dynamics, dynamic impurity accumulation and ambient temperature fluctuations. Drawing on years of experience delivering ten-thousand-ton projects at home and abroad, BICHEM has established a complete, replicable standardized scale-up framework that fully bridges the technical gap between laboratory trials and commercial mass production.
The underlying backbone of BICHEM’s standardized scale-up system consists of three self-developed core patent portfolios covering extractant application, adsorbent application and full-process system technologies. Unlike fragmented industry solutions that only optimize individual process sections, our scale-up logic delivers collaborative design for all working procedures from the outset. The complete standardized workflow is divided into four standardized phases: sample evaluation, pilot verification, industrial modeling and on-site commissioning, with quantitative assessment metrics set for every stage to form closed-loop control standards. During the preliminary laboratory phase, the technical team does not conduct calculations based merely on a single static brine sample. Instead, it collects brine, tailings and mother liquor samples from mining areas across all seasons and production cycles throughout the year, fully recording dynamic data including magnesium-lithium ratio, boron content, salinity and suspended solids to build a dedicated water quality database for each mining zone, which furnishes authentic data support for subsequent process scale-up.
In pilot stage, BICHEM develops a system for standardized pilot test to replicate the material load, circulation flow rate and continuous operation duration of ten-thousand-ton production lines, with 120-hour full-load stability tests carried out to pre-empt potential scale-up risks such as poor phase separation, impurity accumulation and adsorbent capacity degradation. Contrary to the industrial common practice of simplifying pilot workflows, BICHEM integrate resource recovery sections including tailing leaching and lithium precipitation mother liquor recovery into pilot verification simultaneously to align the full-process material balance in advance, thereby preventing overall capacity imbalance caused by newly added recovery sections during mass production. Drawing on comprehensive operating data obtained from pilot tests, engineers construct digital industrial process models to precisely calibrate operating parameters of all extraction, adsorption and membrane treatment units proportionally, eliminating process deviations arising from crude proportional scaling.
Every mature standardized scale-up logic must be ultimately validated through practical deployment in global projects. Up to now, BICHEM has delivered multiple large-scale tens of thousands ton DLE production lines for salt lakes in Qinghai, China and the Latin American Lithium Triangle, all constructed in strict accordance with the unified scale-up workflow.For complex feed materials such as high-sodium and high-magnesium brine and legacy tailing leachate from the Atacama Salt Lake, the standardized process system enables rapid scheme adaptation. The overall lithium recovery rate during commercial operation remains steadily above 95%, while wastewater discharge is cut by 90%, fully complying with local environmental regulations including GISTM tailings management and zero liquid discharge requirements.For existing operational salt lake projects, the standardized lightweight technical renovation system requires no replacement of core equipment. Simply by restructuring standardized parameters and optimizing material circulation, lithium recovery efficiency can be lifted by 10% to 20%, realizing capacity expansion at low capital expenditure.
A sound global localized service system serves as a critical guarantee for the implementation of standardized capacity expansion. The company has set up regional technical centers in Chile, Germany and Singapore, staffed with local technical teams. Tailored to differentiated operating conditions such as high altitudes, large diurnal temperature fluctuations and freshwater shortages, the teams adjust standardized process operation thresholds to ensure the unified scale-up framework is applicable to mining sites worldwide. After project commissioning, standardized operation and maintenance manuals and a remote intelligent parameter regulation system are delivered concurrently to sustain stable long-term performance of production lines.
Driven by surging lithium demand from energy storage and AI computing infrastructure, accelerating the construction of ten-thousand-ton production capacity has become an industry trend for salt lake operators. Reliable and replicable scale-up technologies form the core competitive edge for enterprises to capture market share. Featuring data-driven design, phased control and full-process coordination, BICHEM’s standardized scale-up methodology is backed by self-owned patents and abundant industrial project verification. We provide one-stop technical delivery covering lab testing, pilot trials and ten-thousand-ton mass production for global salt lake clients, helping enterprises evade scale-up risks, unlock lithium resource production capacity rapidly, and build a stable and long-term lithium raw material supply system.
