  1. Mercury is acknowledged as a dangerous contaminant. Exposure to mercury and mercury vapors released from burning the mercury-gold amalgam is a significant environmental and human health concern (Brooks et al. 2007, figure 2). Effects include brain, kidney, and nerve damage, blindness, memory problems, irritability, and tremors.
    Colombia is one of the top three users of mercury in the world. Also Colombia has numerous mercury occurrences: Depts. Antioquia (4), Boyaca (2), Caldas (12), Cauca (2), Cordoba (1), Nariño (7), Quindio (2), Risaralda (1), Santander (5), Sucre (1), Tolima (4), and Valle (2) (Lleras Codazzi 1930; Mutis Jurado 1983; Lozano 1987). And, of the above occurrences, native mercury was specifically indicated in Depts. Caldas (5), Nariño (3), Quindio (1), Santander (1), and Tolima (2) (Mutis Jurardo 1983)
    The Government of Colombia is concerned about environmental contamination from mercury and has attempted to reduce the use of mercury for small-scale gold mining. But Colombian gold miners insist to use mercury.
    Collaboration with Japanese researchers and the efforts of National University of Colombia (CIMEX) scientists in Medellín has resulted in reduction in the use of mercury at intermediate-sized gold mines in Departments of Nariño and Antioquia. Those researchers have demonstrated a mercury-free technology for gold recovery. The ore that comes from the mines is crushed and moved through a series of tanks with chemicals that have physical properties very similar to soap and alcohol and are biodegradable. The process is called “flotation-foaming” and is based on the fact that gold can be made to repel water, and float, while other minerals are attracted to the water in the tank, and sink. The addition of air bubbles into the tank produces the foam that helps concentrate the gold. However, this flotation process only works with ore that has native gold and not with ore where the gold is associated with pyrite. The gold recovered by this flotation method can then go on directly to the smelter (National University of Colombia 2011).
    We propose to AngloGold Ashanti to consider the possibility of using this clean separation method in a big production scale.

  2. Project proposal:
    The high cost of the gasoline in Colombia

    Colombia is a country with big petroleum deposits, in the current commercial context; Colombia is recognized by the petroleum, café and carbon exportation so why is more expensive the gasoline in Colombia than in other countries? The theory of David Ricardo, speaks about the comparative advantages, which aren’t optimally exploited in Colombia.

    Gasoline cost structure by gallon:
    • Ecopetrol receives 52% for refining and distributing the gasoline equivalent to $4.499,15
    • 13.68%, $1.168,12 is received by the governmental state like surcharge, by render service.
    • 11,59%, $989,57 is paid like national tax.
    • 1,01%, $86,42 is part of the community plan destined to contribute with Ecopetrol in their exploration investment.
    • 0,007%, $6,7 corresponds to the marking rate, that is the destination in the combustible for to recognize it between the original and the contraband combustible.
    The most affected sector is the transport sector, it has an impact in the rentability in their profits, especially in the terrestrial and charging transport sector, directly affecting the industrial sector of the country, whose industrializing process is present in the country center with mountain peaks that makes even more difficult the transport process disobeying the industrialization logic of the industry in the port coasts.
    Another problem with high cost of the gasoline is the disincentive offer for the direct foreigner inversion, Colombia losses competitiveness in the transport area compared with other countries of the region.
    In Colombia must be fixed a gasoline price at refining cost and not in an international opportunity cost by the Ricardian Definition in Colombia the gasoline have a comparative advantage compared with other countries, but the national laws don’t let to take an optimal advantage about it for the benefit of the Colombian consumers.

  4. The “gold fever” phenomenon has increased for the last few years due to the growing demand from industries and the high price per once in the market. Colombia, as a rich mineral country it´s been considered as a potencial gold producer and started to explore posibilities to open several mining proyects al over the territory.

    This situation, represents a job opportunity for the population, a better live quality and also, a threath for the national parks located upon the gold deposits an the hydric resources of the country. Also, It´s well known by everyone the potential land affectations by the raise of ilegal mining activities.

    As a consecuence of all illegal activities, the management procedure from those companies are insuficient or null and toxic residues have been spilled into rivers with no advice at all. Chemicals like mercury, are well known by their use in the gold separation process and became one of the most popular contaminants in raiforest rivers.

    Mercury is acknowledged as a dangerous contaminant. Exposure to mercury and mercury vapors released from burning the mercury-gold amalgam is a significant environmental and human health concern (Brooks et al. 2007, figure 2). Effects include brain, kidney, and nerve damage, blindness, memory problems, irritability, and tremors.

    Colombia is one of the top three users of mercury in the world, and also have numerous mercury occurrences: Depts. Antioquia (4), Boyaca (2), Caldas (12), Cauca (2), Cordoba (1), Nariño (7), Quindio (2), Risaralda (1), Santander (5), Sucre (1), Tolima (4), and Valle (2) (Lleras Codazzi 1930; Mutis Jurado 1983; Lozano 1987). And, of the above occurrences, native mercury was specifically indicated in Depts. Caldas (5), Nariño (3), Quindio (1), Santander (1), and Tolima (2) (Mutis Jurardo 1983).

    The Government of Colombia is concerned about environmental contamination from mercury and its been attempting to reduce the use of mercury for small-scale gold mining. But governmental efforts haven´t been productive and illegal mines keep using mercury as a main component in the gold separation process.

    A collaboration with Japanese researchers and the efforts of National University of Colombia (CIMEX) scientists in Medellín resulted as a reduction in the mercury implementations at intermediate-sized gold mines in departments of Nariño and Antioquia.

    Those researchers have demonstrated a mercury-free technology for gold recovery. The ore that comes from the mines is crushed and moved through a series of tanks with chemicals that have physical properties very similar to soap and alcohol and are biodegradable. The process is called “flotation-foaming” and is based on the fact that gold can be made to repel water, and float, while other minerals are attracted to the water in the tank, and sink. The addition of air bubbles into the tank produces the foam that helps concentrate the gold. However, this flotation process only works with ore that has native gold and not with ore where the gold is associated with pyrite. finally the gold recovered by this flotation method can go on directly to the smelter (National University of Colombia 2011).

    As an inminent solution for river pollution and human intoxication by mercury, we purpose to AngloGold Ashanti to consider the possibility of using this clean separation method in a big production scale, making as a result a decrease in contamination and a better residues management.


    Teacher, I would like to know your thoughts about the essay before exposing it tomorrow. Thanks.
