12 supergene ore and gangue characteristics,mineralogy and mineral assemblages. in the traditional view, supergene ore and gangue minerals are the products of reactions between hypogene sulfide minerals and descending, acidic meteoric waters these processes take place at or near the ground surface in subaerial environments (guilbert and park, 1986). in vms deposits,.textures of oreminerals slideshare,jul 10, 2017 textures of ore_minerals 1. 1 geol 481 earth resources el-shazly, a. k., 2004 textures of ore deposits and associated features importance of studying textures textural identification and interpretation for ore deposits and associated gangue minerals are tools necessary for understanding the processes involved in the genesis of these deposits, which in.Get Price
in mining, gangue is the commercially worthless material that surrounds, or is closely mixed with, a wanted mineral in an ore deposit. the separation of mineral from gangue is known as mineral processing, mineral dressing or ore dressing and it is a
as nouns the difference between ore and gangue is that ore is rock that contains utilitarian materials primarily a rock containing metals or gems which -- at the time of the rocks evaluation and proposal for extraction -- are able to be separated from its neighboring minerals and processed at a cost that does not exceed those materials present-day economic values while
the ore mineral is always mixed together with unwanted or economically valueless rocks and minerals. these rocks or minerals are generally known as gangue. usually, the ore and the gangue are mined together. further separation of ore from the gangue process is known as mineral processing.
heap leaching accounts for a fifth of global copper production, sourced primarily from porphyry ores, yet metal recoveries are often not optimal. gangue, and its interaction with acid, plays an important role in such processes. thus, a proper understanding of gangue minerals present in the ore, their textural relationships relative to particle size distribution, reactivity with acid under
oct 12, 2020 many swedish mines use parts of the gangue as a resource, e.g. as aggregate for road construction or to refill mined rock chambers and open pits. tailings. tailings are a fine-grained residue, mainly consisting of gangue minerals that remain after the separation of valuable minerals and metals from their ore in a processing facility.
if the gangue mineral in an iron ore is predominantly quartz, reverse flotation is usually used in the cleaning stage to improve the concentrate grade. figure 9.13 presents a typical flow sheet for processing an oxidized iron ore containing about 30 fe using a combination of slon magnetite separators and reverse flotation. the ore is mainly composed of magnetite, hematite, martite,
after raw ore is mined, it is ground up and processed in such a manner as to separate the ore and gangue minerals, often by taking advantage of the chemical, density, magnetic, or surface adsorption differences among the particular minerals. for example, cyanide solutions can be used to preferentially dissolve gold from ore, and many base metal
aug 14, 2019 (ii) ores - those minerals from which the metals can be extracted conveniently and profitably are called ores. (iii) gangue - the unwanted impurities like sand, rocky material, earthy particles etc., present in an ore are called gangue. (b) before extracting metal from an ore, it is necessary to remove these impurities (gangue) from it.
an ore is a mineral from which metal can be extracted conveniently and economically. br ( c) gangue. the earthly impurities such as sand, limestone, rocks etc. associated with minerals and ores are collectively known as gangue or matrix.
1) mineral -the naturally occuring compounds of elements are known as mineral. 2) ore- the mineral from which an element can be extracted easily and profitably is called an ore. 3) gangue- the impurities present in ore such as sand rock etc is known as gangue. answer verified by toppr. upvote (0)
very demanding quality parameters that differ according to the kind of application. chromite ore cannot be usually sold as it is and, therefore, some kind of ore beneficiation is required in order to separate chromite from gangue minerals. the most commonly used beneficiation methods for chromite ores are the gravity methods, such as the
q.6. define the terms- (a) mineral (b) ore (c) gangue. ans. mineral-the inorganic element or compound, which occurs naturally in the earths crust is called mineral.for example, copper pyrites (cufes 2), cuprite (cu 2 o), etc. are the minerals of copper. ore-the mineral from which a metal can be extracted profitably and conveniently is called an ore.
ore, as mined, contains ore minerals, gangue minerals, and country rock. a mass of mineral matter is not considered ore unless one or more of its ore minerals can be recovered on a profitable basis. as originally used, ore minerals were metal bearing (see metallic minerals).more recently, nonmetallic minerals of commercial importance are considered ore
many different mineral commodities are important to modern society. however, when mineralogists think about mining, they are generally thinking of ore minerals that are the sources of important metals, or of minerals that have specific, highly valued properties (e.g., asbestos, micas, potash, and gems of all sorts).that is what we will focus on in most of the rest of this

the mineral deposit is not only related to ore minerals. they always have valuable minerals with them. these are called gangue minerals. an ore deposit rich enough to work with profits is called an ore deposit and is called ore minerals plus gangue ore in an ore deposit. vein-mineral-deposits. note.
all minerals are not considered as ores, but all ores are also minerals. examples bauxite al 2 o 3.2h 2 o is the ore of al, copper pyrite cufes 2. gangue. in chemistry, a gangue is an unwanted substance or impurity that surrounds the mineral in an ore deposit, such as sand, rock, or some other material.
mar 02, 2021 an ore contains multiple minerals in combination its a mixture of valuable components and gangue. the ore grade refers to the fraction of a useful element within the ore. it can also be used for gangue as the proportion of a non-valuable substance, but generally, when we use the term grade, we mean the grade of a valuable element.
3. what is mineral ore used for? ans ore is a deposit of one or more precious minerals in the earths crust. the most important ore deposits, such as copper, silver, and iron, contain metals that are essential to industry and trade. copper ore
dec 04, 2006 most ore minerals are abbreviated according to chace (1956) and most gangue minerals according to kretz (1983). following chace (1956) and the dominant use in publications on economic geology, and in contrast to kretz (1983), mineral abbreviations are written in lowercase. native elements are capitalized.
4.2 ore-gangue minerals paragenesis the paragenesis for a mineral deposit or a ge- netically related group of deposits is inferred from the mutual relationships among the min- erals and assemblages misra, 1999. the inter- pretation of microscopic textures of ore miner- als is very useful to prepare the paragenesis di- agrams of those ore minerals.
dec 20, 2020 difference between mineral and ore gangue and tailings the most known examples of gangue minerals are quartz, calcite, mica, pyrite, feldspar, etc. usually, gangue took the name of a family group of minerals such as iron oxide gangue, silicate gangue, carbonates gangue, etc. for example, silicates gangue may include quartz, feldspath, and
