In-place leaching of primary sulfide ores: Laboratory leaching data and kinetics model
TL;DR: In this paper, the results obtained in laboratory leaching studies of primary copper sulfide ore in sulfuric acid systems pressurized with oxygen are interpreted by a computerized geometric model involving the movement of a reaction zone through the ore fragments.

Dielectric properties of Jovian satellite ice analogs for subsurface radar exploration: A review
Elena Pettinelli,Barbara Cosciotti,Federico Di Paolo,Sebastian Lauro,Elisabetta Mattei,Roberto Orosei,Giuliano Vannaroni +6 more
TL;DR: In this article, the authors present a complete range of potential ice types that may occur on these icy satellites to understand how they may affect the results of the proposed missions and select the most suitable data to compute dielectric attenuation, velocity, vertical resolution, and reflection coefficients for such icy moon environments, with the final goal being to estimate the potential capabilities of radar missions as a function of the frequency and temperature ranges of interest for the subsurface sounders.

Kinetic studies of the reaction between Cr23 C6 particles and Cr2O3 particles
TL;DR: In this paper, the rate of reaction between Cr23C6 particles and Cr2O3 particles which yields metallic chromium was studied and the molar ratio was maintained at 1:8.

Multistep Reduction Kinetics of Fine Iron Ore with Carbon Monoxide in a Micro Fluidized Bed Reaction Analyzer
TL;DR: In this article, the reduction kinetics of Brazilian hematite by CO are investigated in a Micro Fluidized Bed Reaction Analyzer (MFBRA) using an analyzing method based on Johnson-Mehl-Avrami (JMA) model at temperatures of 973 K (700 K), 1023 K (750 K), and 1123 K (850 K).

A simple kinetic model for sulfuric acid leaching of copper from chrysocolla
P. C. Hsu,Lawrence E Murr +1 more
TL;DR: In this article, the results obtained in room temperature laboratory leaching studies of lowgrade chrysocolla are interpreted by a kinetic equation of the form 1−(1−R)1/3=(1/αKr c) ln (αkKC 0t+1) derived on the basis of a special form of the shrinking core model and assuming chemical reaction control.

Application of A Generalized Rate Equation to the Gaseous Reduction of Iron Oxide
B.B.L. Seth,H.U. Ross +1 more
TL;DR: In this paper, a generalized rate equation based on the assumption that reduction is controlled by both the oxide/metal interfacial area and gas diffusion mechanisms was applied to pure ferricoxide pellets pellets of 7.5mm dia reduced in H at 750°C.

The Effect of Calcium Carbonate on the Reducibility of Iron-Oxide Agglomerates
P. K. Strangway,H. U. Ross +1 more
TL;DR: In this article, the effect of lime and calcium carbonate on the reducibility of iron oxides was investigated in a loss-in-weight furnace at temperatures ranging from 600 to 1000°C.

The Effect of Lime on The Reducibility of Iron-Oxide Agglomerates
B. B. L Seth,H. U. Ross +1 more
TL;DR: In this paper, the effect of the lime additions upon the reducibility of iron oxide was studied and the mechanism of reduction of ferric oxide is different in the presence of lime from that of pure iron oxide.
