INTRODUCTION
Rollfront deposits are an accumulation of minerals in reduced permeable sandstones or other sediments between mostly reduced and pervasively oxidized environments [1]. Rollfronts are classified as epigenetic mineral deposits, i.e. their genesis occurred after hosting environment was created, that that often can be found in arid areas and trapped within permeable sedimentary...

INTRODUCTION
The Honeymoon Uranium Project is an acid In-Situ Recovery (ISR) mine in South Australia. The project contains three deposits; Honeymoon, Jasons and Goulds Dam. The measured resource consists of a total of 6.5 Mlb U3O8 (2.9 kt U) at an average grade of 1720 ppm U3O8 (1460 ppm U), with total resources (measured + indicated + inferred) of 63.3 Mlb U3O8 (28.8 kt U) at 660 ppm...

While processing deep production horizons of the uranium deposit Inkai being developed using the technology of drill hole in situ leaching (ISL) it is essential to support high rates of pumped off well sites, to increase terms of interrepair working cycles of production wells, to keep the opportunity for reduction of number and duration of repair and renewal operations (RRO).

INTRODUCTION
Uranium deposit Nyota is located in the southern part of the United Republic of Tanzania. The geological setting of the deposit and its hydrogeological properties allow to consider part of the Resources as potentially amenable for mining by in-situ leaching (hereafter referred to as “ISL”). In 2015-2016 Uranium One Group conducted a range of studies for evaluating of the...

INTRODUCTION
An important condition of uranium mining industry development is environmental monitoring and ecological security of field development.Тhe well in situ leaching (ISL) method has a less impact on the environment than traditional underground and open-pit mining methods. The uranium extraction is carried out by the technological wells system construction that open a productive...

‘INTRODUCTION’
Roll front deposits are an important global source of economic uranium ore, commonly mined using in situ leach (ISL) methods. The simplified conceptual model for roll front formation calls for the reductive precipitation of U(VI) to U(IV)s as oxygen-rich groundwater interacts with subsurface reductants such as iron minerals, sulfide and anaerobic microbes, forming reduced U...
