Xoma's collaboration with Boliden Rönnskär moves forward to phase 4 in the operating model the company uses, according to a press release. The decision is made in light of promising results from the in-depth tests and analyses that have been carried out. The transition to the next phase is, according to Xoma, an important step in the commercialization of Flow technology. "In this phase, Xoma is working to compile all test results, carry out in-depth calculations, and produce a structured, customer-specific decision basis. The material will form the basis for a potential decision on establishing a pilot plant, based on Flow technology," it says.
