## About

Rock Zero is a startup focused on commercializing a new, environmentally friendly, and potentially cheaper method for extracting lithium from silicate minerals. The process uses a weak acid, ammonium fluoride, to dissolve these minerals, freeing lithium and other valuable materials like alumina and silica. This approach avoids the high temperatures and dangerous chemicals often associated with traditional hard-rock mining and offers an alternative to geographically limited brine extraction. The company aims to be the lowest-cost lithium producer globally and plans to scale its technology for broader mineral extraction applications.
