RECICLAGEM DOS METAIS
QUIMICA 12ºano
Principais aplicações do metal reciclado
Ferro
Aço
Alumínio
Chumbo
Introdução
Os metais são matérias-primas não renováveis.
A formação dos minérios teve origem na própria formação da Terra. Não é possível criar condições semelhantes para a formação de novos minerais.
Embora as reservas minerais variem muito de metal para metal, elas são sempre finitas. No caso de alguns metais de maior utilização, como, por exemplo, o cobre, são bastante escassas para o consumo atual.
A reciclagem é necessária e urgente
Backpak
Para obtenção dos metais através dos minérios é feita a redução do minério, ou seja, a separação do metal dos restantes componentes.
Este é um processo primário e é realizado a altas temperaturas com elevado consumo energético.
A reciclagem do metal é considerada um processo secundário de obtenção deste material, que neste caso, consiste na fusão do metal já usado com consumo de energia menor.
Importância da reciclagem dos metais
O metal reciclado tem praticamente todas as características do metal comum. Devido à sua estrutura cristalina os metais podem ser reciclados várias vezes, dado que essa estrutura não se degrada durante o processo de reciclagem.
Conservação dos recursos naturais
Diminuição da poluição
Economia de energia
Redução de resíduos
A reciclagem dos metais contribui para a diminuição das emissões de gases de efeito de estufa, ou seja, contribui para a redução da poluição atmosférica.
A reciclagem dos metais reduz a necessidade de exploração de minas, promovendo a economia das matérias-primas.
A reciclagem dos metais é vantajosa em termos energéticos, pois envolve menos etapas do que a exploração do metal a partir das suas fontes naturais diminuindo o uso de combustíveis fósseis
A reciclagem dos metais tem vantagens a nível ambiental, pois permite diminuir a área degradada pela extração de minério, assim como, evitar o depósito dos objetos metálicos rejeitados nas lixeiras e consequente contaminação das águas.
Pelo facto de os metais poderem ser reciclados, observa-se uma diminuição do consumo de recursos naturais e da diminuição da poluição, contribuindo, assim, para um planeta mais verde.
Aplicações de alguns metais reciclados
Aço Reciclado
É usado no fabrico de uma ampla gama de produtos: automóveis, utensílios domésticos, estruturas metálicas usadas na construção civil e embalagens.
Alumínio Reciclado
É usado em diversas aplicações, incluindo latas de bebidas, embalagens, componentes eletrónicos, janelas e portas e peças de aviões

You have explored the entire island, managed to build a raft, but now you can't remember where you left your backpack and you'll need it before you can leave. On the map, you can see the places where your backpack might be.
Drag the parts of the map to find where you left your backpack and be able to escape from the deserted island.
