Design and Specifications for the Highland Regolith Prototype Simulants NU-LHT-1M and -2M [PDF]

open access: yes
The first two prototype lunar regolith simulants were to replicate characteristics of the lunar highlands. A major change from initial plans was to use an estimate of typical Apollo 16 highland material rather than a specific core.

Thermochemical Effects of Flux and Coke Amount on the Smelting of Low-Grade Chromite Sand to Ferrochrome

open access: yesBiointerface Research in Applied Chemistry
Ferrochrome serves as a vital ferroalloy product, which functions as a fundamental alloying material in stainless steel production due to its corrosion resistance properties. However, its production needs high-grade chromite ore (46–48% Cr₂O₃) with a chromium-to-iron (Cr/Fe) ratio above 2.8, which creates problems because of declining reserves.
