A consignment of magnetite concentrate, produced from ore composite samples generated from the Reverse Circulation drilling program completed in April, was delivered in July to SMS group in Germany for equipment selection test work, which is progressing.
There were proposals to scour the seabed 9 to 15 kilometers from the shore and extract magnetite from an area of 5,000 hectares.-Inquirer Research
Therefore, this article describes the development of a nano-structured composite in which the IPC (PAS/BSA = 25/75) was used as the polymer matrix and pre-synthesized magnetite particles were chosen as the magnetic filler.
"Using our magnetite resources, using local materials, we can make steel." The findings of the collaboration project were presented at a lecture series conducted by the Chamber of Mines of the Philippines in partnership with the Philippine Council for Industry, Energy and Emerging Technology Research and Development at the Crowne Plaza Manila Galleria in Pasig City recently.

For the oxidation of NF616 at 600[degrees]C, the oxygen activity in the Fe-Cr spinel layer evolves from 2 x [10.sup.-25] to 1.41 x [10.sup.-23], and the diffusion process follows an interstitial mechanism; the oxygen activity in the magnetite layer evolves from 1.41 x [10.sup.-23] to 2.57 x [10.sup.-16], and the diffusion process varies from a interstitial mechanism to a vacancy mechanism.
